Even though this has been explained many times since the whole hullabaloo, I’ll assume you’re genuinely unaware and/or perhaps got rage-farmed by someone else’s meme. 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. There is net new support by Canonical that covers community-supported packages too which is available with Ubuntu Pro subscription. Therefore Canonical hasn’t removed any existing, previously free security support. In addition, this newly added security support is available for free for up to 5 machines and it lasts for 10 years.
