I understand and almost completely agree with what you're saying, but there are plenty of developers out there that provide meaningful improvements to their games even after they have your money. For some, it's a labour of love and also a matter of reputation.

This is EA, however, so your point completely stands.

As much as I enjoy the series, they need to move away from UE or put a lot more work into optimising their games.

Fallen Order still suffers from traversal stutter and they've somehow made it worse in Survivor. They need to fix their current games before expressing interest in making new ones.
