The availability of the tools are a main reason why I purchase e-books. When a vendor (Apple) made it impossible for me to use them, and I could no longer read my purchases on my various devices, I stopped being their customer (and it irritated me enough to switch from iOS to Android).
So, yes, I would certainly welcome if more publishers and vendors abandoned DRM. Making DRM more inconvenient (say, online authorization), it would backfire. There is no shortage of alternatives, such as copyright-free books, and there are sellers like Baen who don't use DRM at all.
I generally have no lack of ways to spend my money.
