I think you’ve got it the wrong way around.

They can only make these patches because large enterprises wanted them and were willing to pay for them, and they have found a nice way to make the patches available free to you and me. If they made them free for large enterprises too, that funding would go away and we would all lose them.

Also, the extra security work on universe means there are more people who can handle the main repo even better. So even non-Pro users have benefitted.
