Good luck with that. I'm sure Adobe doesn't give a crap if you like their software or not, as long as you buy it, and probably barely acknowledges Gimp. (if at all) I'm sure they're under the mistaken impression that people
need their software. Though, the problem is that a lot of people probably think they need it too. With a lot of 3D artists, Gimp is a dirty word, even though I'm sure many of them could find the same functions they have in PS for free in Gimp. Though, there are a lot of photo editing programs out there. There are way more of those than there are programs like AfterEffects and some of the other stuff Adobe makes. My first taste of photo editing was a program called Photo Deluxe, and a program called Image Folio. They came with a scanner I bought in '98 or '99.
The only version of Photoshop I've ever used is the mobile one, and only because it came with my tablet. Though, truthfully, I'm not impressed. I don't know if it's more limited than the PC version, which I'm sure it is, or if editing photos on a tablet just sucks.
And the high school I studied in had Windows 98 computers where I learnt the basics of computing.
Lucky. We had Windows 95. In the one class I had, the teacher told us right at the beginning she wasn't quite "up to speed" on Win95. The teacher. Didn't know Win95. In 1997.

Anywho, that was my first taste of computing, then I bought my first computer on Black Friday 1998.
