Piracy: ꜱᴀɪʟ ᴛʜᴇ ʜɪɢʜ ꜱᴇᴀꜱ

Maybe bandcamp and youtube?

Funkwhale is a federated music sharing platform. In addition to some of the good suggestions here, maybe add that into your mix.

I release music. I use a low cost platform for distribution. There are free ones. I understand your position because I feel similarly.

I never expect to make money or get recognized, but I think my music is good enough to share. To do that, you need a distributor and to be on the major platforms.

Look into Soundrop. You can also put your stuff on bandcamp for free, but at least get it out as widely as you can.

Read that for a start. And maybe consider sharing your work under a nice license. You can also check out platforms like Jamendo, Bandcamp, the Internet Archive... And as far as I understand archive.org will even handle generating some torrents for you.

A lot of people use bandcamp.. probably the least corporate of the online platforms

How much do you know about piracy? VPN, torrenting client, etc..

Did you release it through a publisher of some kind? If not, it wouldn't matter because you have the full rights and the onus would be on you to take legal action in anyone that downloaded it.
