I don't think this is so very weird. For most users, popular products are likely to be more future proof, so choosing them can grant a sense of security.
Psh, the average user clearly hasn't heard of the Lindy effect[1]! /s
Sarcastic condescension aside, I was really taken aback by the sheer fanfare Notion had when it released. In my circles, adoption was driven largely by one designer; in fairness he's always excited about new technology but when everything is the best thing since the iPad, a few eyebrows get raised. I'll bet lunch money they would be first to migrate to the next-hot PKM tool for the slightest feature offering.
As for me, I want to spend the least amount of time adapting my workflow. My workflow must help me work, not be something I am constantly working on. So it's all about inertia for me; Evernote needs to fuck up big before I leave.
In fairness, there was a time (around 2015s) when Evernote had frustrating bugs. Even beyond that, their editor was also subpar for such a long time. But I'm really satisfied with the current version which, I suspect, came about due to the threat Notion posed to their user numbers. Yay for market competition, I guess somehow I still benefited off Notion. :)
It's probably better being hyped before waning than just waning, I guess.
