I’ll assume you’re genuinely unaware

I’m perfectly aware of what Ubuntu Pro is, and the difference between Ubuntu main and universe.

The current meme implies that Ubuntu/Canonical have actively disabled safety/security features in the form of withholding security updates, unless you pay for Ubuntu Pro subscription. The Ubuntu package support hasn’t changed with the introduction of Ubuntu Pro. The packages that were supported by Canonical prior to this are supported the same way today. The packages that were community supported prior to this are supported the same way today. Without Ununtu Pro.

If you think the meme implies that, then surely you must think that the message printed by Ubuntu’s apt upgrade command in the screenshot implies that too, right?

One of the packages listed in this screenshot is libavcodec, which is required by things like VLC (which is in Ubuntu universe, which is enabled by default).

If you think it is perfectly fine for Canonical to do the work to patch that library and then withhold the security update from the vast majority of Ubuntu users who won’t sign up for Ubuntu Pro… we’ll have to agree to disagree.
