What’s Ubuntu’s “particular madness”?

I remember that it does too much, but without specifics. It's been 4+ years since I touched Ubuntu.

They used to be a little FOSS-only

I vaguely remember that "Amazon lens" for Unity, I don't think they ever were that much FOSS-only.

No matter how many games run on linux, it won’t be enough because there aren’t ever going to be linux exclusives.

It's fine. That'd still be goal fulfilled.

Office sounds like a big deal, but Apple managed to prove you don’t need it.

How so?

There’s nothing wrong with Libre- or Open- except the complete lack of advertising and passive training to its nuances that we get from MS and Apple office products.

I recently had a problem with LO, while editing a document with lots of math formulae - from time to time while adding a formula about half of others (in the whole document) would just become empty.

Not sure something like that would happen under Apple suite's analog of Word, whatever it's called.

It’s not that linux can’t win on games or office. It’s that the game is rigged against it on both.

With that I agree, somewhere in 2012 I somehow realized that it's already much better than the alternatives, and yes, for a housewife's desktop just as well, if one's honest and thinks of their own needs.

And if one's comparing it to advertising of the competing commercial products, then it's hopeless.
