Piracy: ꜱᴀɪʟ ᴛʜᴇ ʜɪɢʜ ꜱᴇᴀꜱ

How?

By the way, yes, it is.

it would require government intervention. Where a regulation must declare that ads must clearly be labelled as ads, so that adjustments can be made by detecting when is the ad segment happening.

This one might be harder, if YT just sends the ad like it was part of the video file, generating it on the fly, it's a lot harder to detect, and probably not too hard for them to do, but breaking timestamps is pretty bad for some types of videos, like tutorials.

The last time Google pulled out all the stops to fight ad blockers, I had to update uBlock Origin every now and then until the whole thing passed. That's all.

So I'm not worried. But I am amused that they keep making ads more obnoxious, which pushes more people to use ad blockers. I didn't even use sponsorblock until a particularly egregious bit of native advertising. They could probably gain ground by just making ads less irritating, but they absolutely will not.

The state of whether it's an ad has to be somewhere clientside as the ads can't be skipped by the user.

Ads need to be tailored to the user when delivered

1. It does not. If you install a new browser and open YouTube the first time, they'll be able to show ads to you
2. They could be tailored based on other factors too, like country, region, or even household by the IP

I think the backend could just generate the ad ridden video feed for the specific user. Most probably it would be very resource intensive, but I can only hope so.. but then I also don't know much about HLS and other fragmented streams so it might not be a performance problem at all.

like a linked list

I think the full list of chunks is (currently) known beforehand. That's how yt-dlp can download on multiple threads, but also how it can show the number of total fragments relatively quickly on the progress bar

yeah that makes sense. i was thinking maybe youtube had servers to decide what chunks clients would get, maybe by looking at whether or not they are premium users first. but anyway youtube still needs a way to differentiate between ad chunks and video chunks, otherwise we would just be able to skip 10 seconds through all the ads. surely that can be exploited somehow.

... which is why youtube has recently started blocking non-logged in users

I can't morally justify blocking ads and viewing their content for free.

I can't morally justify anything they are doing, and have been doing for many many years already. Yet I use their public services because they are unavoidable. But I would never give money to such a company.

I'm pretty lucky not liking most YouTube style content these days, so don't consume too much of it like I used to. Lot of the creators feel like AI with the same phrase of if you are new to the channel like and subscribe and ring the notification bell...blah blah blah. And then drag out info that can be said in a minute into a 10 minute long ramble for the algorithm.

YouTube these days is more for music or checking out a part of a game I'm stuck on these days from a creator with like 1 sub putting up a 10 second long clip that gets straight to the point. Those guys are the heroes over the 5+ minute long uploads of the same content in comparison that has you have to dig into the comments to find where to skip to.

I'd get premium if they weren't so insistent on bundling in bullshit I don't want or care about to justify the high price. I put up with enough of that from cable TV. I'll pay when there's an ad-free tier that doesn't do anything else and is a reasonable price for "the service that's free with ads, but without ads". If there was a per-device premium tier that I could throw on my Roku, and all my family members could have premium when they stream from there, I'd pay for that. I'd pay for family tier if it didn't have the dumb single-household rule which screws over truckers and those who travel for a living.

Google has options they could take to convince consumers to pay to not see ads, but there's no creativity left there, no effort to court the market or adapt the service and prices to what potential customers need and are willing to pay. And it's because they believe they are the market, and want to keep it that way.
