Being able to sell FOSS is one of the freedoms “free software” refers to.
Honestly though I think the thing that struck me the most and I found kind of scummy was their “value statement” where they were advertising the OS by comparing it to the prices of the proprietary software is includes alternatives to. You misreading the website wasn’t an accident, they designed it in a deceptive way IMO.
If they were more honest about it, I wouldn’t have any problem with them charging for the convenience of having everything pre-bundled. Of course you could set everything up yourself, but Linux is notoriously finnicky. People want a complete experience, they want support. They want the slick branding.
All of your temporary privacy addresses will be coming out of the same subnet, so it’s clear they all belong to the same people.
Ultimately the privacy extensions are just bringing IPv6’s privacy back in line with IPv4, because without the privacy extensions every single device has a separate IPv6 address based on its MAC address whereas in IPv4 most consumer networks have every device sharing a single IP.
