Hey thanks for posting this. I've bookmarked it to watch within the hour.
I'm interested to see if these are really businesses under threat from Microsoft or if it's businesses looking to eliminate competition from USA and push their own products. I'm not a fan of MULAFAANG pushing a monopoly but I'm also realistic that politicians will always be motivated to do what politicians do best.
EDIT: Not even that far into the video yet...So I live in the USA and I've visited a Microsoft campus when I was in Washington. And the premise of what is being presented is laughable. I said as a system administrator back in 2015 that going into the Microsoft cloud azure was bullshit and not a good idea, and turns out today that is still the answer. If these departments wanted to use Linux that is an internal decision not one reflective of Microsoft. LLDAP (easy managed LDAP service) exists in FOSS. So does Mailcow. Everyone loves to masterbate to how "bad these companies are", dude you CHOSE them. There are parts of Microsoft's footprint that are good like their ability to staff teams to work on security, keeping NPM, github, and pypi safe. But they also have a lot of malware-like components in their services/OS that collect data in the same way a virus would.
I just don't like this premise of purchasing someone's product and then vilifying that product as if they had no other choice. I understand that its not entirely with that intent, its more to start a conversation about it, but damn does it ring that way when I saw self hosting in 2015 & IT departments as the answer.
EDIT2: Why are talking about the cloud, then pivoting to saying that Microsoft won't release the source code for Windows? Lol. These are two separate topics, and the author of the video didn't attempt to pose it as one. I am disappointed by the author to present the information that is reasonable and understanding of both their own culture and display a lack of effort in their own administration to use existing FOSS products. No one has a gun to your head. I've migrated between 5 different clouds and solutions over the last few years for my own company's infra.
