And that arrogant "I understand it, why don't you?!"-attitude is exactly what's so often the main issue in the design process of open source software.
I'd recommend watching this recent talk by Tantacrul, the design lead for MuseScore and Audacity. In it, he shows some videos of first-time user tests he conducted for Inkscape recently. It's really fascinating to see, how users fail to do what they want because of confusing UX choices. And often it isn't even that hard to fix. But open source image editors are just full of these little annoyances by now, which really smell like the result of inadequate user testing. And no professional would prefer to work all day with software full of little annoyances when there are alternatives.
I mean, just try adding text in Krita, for example. There's a giant pop-up where you have to format your text without actually seeing it on your image. That's just klunky and far more time consuming than a WYSIWYG approach would be.
Oh boy, here I go ranting against misinformation about recycling again.
Your claim that 60% of these bottles will be burned is false. The recycling quota for single-use plastic bottles in Germany is 97.6% (2023; source).
60% was the quota of all non-recycled plastic packaging material combined, back in 2018. This quota has further decreased since, and is now at about 30% (2023, source), so almost 70% of all plastic packaging in Germany is recycled. It's still not perfect, but far, far better than just burning everything.
Recycling isn't an easy and cheap process, but it can definitely work and be steadily improved, if it's properly implemented. I'm so tired of this dumb suggestion, that recycling is bad because it's not perfect (or, in the case of the US, full of corruption). Every bit of plastic that isn't polluting the environment is a win. And recycling is definitely helping with that. As opposed to propagating false information on the internet.
