If you limit your actions in life to only "the things that cause me zero inconvenience right now", you will be played like a fiddle your entire life. Literally everyone who wants to control in any way for any reason knows this one simple trick, and I don't just mean the big things, but the little things like marketing tricks, cell phone contracts, etc.

If you get used to the need to occasionally take a short-term hit for a long-term win, it gets easier over time. It's a good thing to practice, in all senses of the term.

If everyone actually did switch, the options would become better through the increased resources the alternatives would get.

Seriously. It's losing many weeks of your life to retrain in alternatives to Premiere, Illustrator, Photoshop, After Effects. If not months.

Not to mention it's often simply not a choice at all, because you have to collaborate with people who only work in those file formats.

If I'm reading the ToS correctly, it implies that a creative who uses Adobe products is granting Adobe a license to all content anyong creates on their platform. So this is something that can happen:

1. Alice signs the ToS, granted Adobe a non-exclusive license to all work created using Adobe products.

2. Disney (or insert your own litigious company here) hires Alice to do some art. Alice and Disney sign a contract that says Disney owns the IP to the art outright and Alice retains no rights to the work.

3. Alice makes the art. Alice gives the Art to Disney. Disney pays Alice.

4. Adobe thinks the art is great, and puts the art on stock.adobe.com, using the license that Alice granted them.

5. Chuck's Ads hires Bob to do some art; they sign a contract that allows Bob to use stock art for some of the elements.

6. Bob makes the art using stock art; specifically using Alice's art which Adobe has put on stock.adobe.com.

7. Bob sells the art to Chuck's Ads. Chuck's Ads runs the ad nationwide. The company who is making the advertised product likes the art and puts it on the box which is sold in stores.

8. Disney's flesh eating lawyers see the ad and start suing everybody.

What happens to Alice? From where I sit, it seems like she gets hit by a breach of contract; she granted Adobe a license which she didn't have the right to grant.

What happens to Bob? Certainly Chuck's Ads will get sued to Disney, and they won't be happy about it. It stands to reason that Chuck's Ads and/or Disney will sue Bob for breach of contract and/or copyright infringement respectively.

You're correct. I'm not saying you're wrong. It is naive to assume people can just "Cancel Adobe." But it's also naive to assume people who get paid to use this product suite don't legally have to.

Plus there really is no replacement for After Effects.

Also I have 14 years of prior projects that I sometimes need to reopen, so canceling just isn't an option.

yes

but also by today there are a lot of good alternatives many more and much more mature ones then in the past
