Edit notice: I completely overwrote the initial version of this comment, which said I couldn't find these posts, because I realized I was using the wrong search time terms and found what parent mentioned.
Appimage has solved the distribution on Linux problem, software packaged as Appimages are as easy to run as an exe on Windows, and no additional software is required (unlike Flatpak & Snap).
The forum comment is from 10 years ago. I have no idea if it still (or ever) accurately describes Abobe's internal decision-making. I do not and have never worked for Adobe, so regardless of the merits of your assertions I can't change anything.
That said, if I had to make an assumption about Adobe's perspective, I'd assume that the position of many linux users that desktop software shouldn't require a recurring subscription was (and is) the main obstacle from Adobe's perspective, not distribution.
