I think this shows that you don't fully understand UI/UX and its importance/role in modern software creation. Moreover, you're conflating your opinions about Spotify with an industry. This would explain what I consider to be an mis assessment of the situation.

As someone close to UX my entire life, Figma is a well positioned and useful app that has no decent substitute on the Adobe side. It has market share and potentially a huge data moat giving them a leg up on the "AI Designer" problem. Now more than ever, it is worth a lot.
