How about in a year or so, after they've shown they can be trusted. Putting 5e into the CC isn't going to be terribly useful if it turns out that they are going to make One has it's own SRD and/or isn't actually compatible.
Except they didn't just remove access to the pears. They were also trying to stop people from having access to completely different trees--e.g., those companies who use the SRD but don't produce 5e/d20-based games, like Fate. And they wanted to disallow the use of animated assets on VTTs that weren't even owned by them, just so D&D players would have to use the D&D VTT (whenever that comes out), even though that would very likely cause those VTTs to lose so much money they might have to shut down or raise prices significantly for people who want to use them for non-D&D games.
And your "pear tree" analogy isn't quite as apt as you think anyway for another reason, because people have used that license to make many different games under their own companies. It would be more like if the people who picked the pears planted the pear's seeds and grew their own trees, using their own labor and on their own property, and then WotC tried to cut them all down, and also tried to burn down every fruit stand and grocery store so that the only place one could get pears was from them.
