Yes, we started purchasing very early on with DVDs, when they were the new thing (I started with Betamax and VHS ;) and we never had any reason to quit using them. My spouse and I tried streaming very early on but after a few interesting years they quickly devolved into a very unchallenging crap factory merely trying to promote this or that type of ideology (we both dislike propaganda, no matter who's "camp" it's pooped from) so we cancelled and went back to our more valuable than ever collection of (great) movies on DVDs.

Like you: no BR discs because, as a GNU/Linux user, I don't want to bother with their DRM crap.

The same with CDs, btw: we also own a large collection of those. With a difference: it's 100% ripped, so I don't need to actually load the discs.
