Non developers typically don't think about these things. They just suffer them subconsciously or accept the situation as something they can never change anyway and go on with their lives. You have to ask them to find out.
And I also hear developers complain more about performance issues than non developers.
I've watched Logseq (note app) go from a perfect little browser-based app that did exactly what I wanted--block-based markdown notes synced through git--to an app with dozens of features that are pure bloat for me that I can't use in half the places I need it because I cannot install apps.
It was an interesting process to watch start, because people were like "finally an app!" and "moving on from 'just' a website!" but without any real justification for it. The app itself was the accomplishment.
And I should note the Logseq app is a good piece of work. In absolute terms it's great. It is, however, not what it used to be and not really what I want. I'd like to fork Logseq, deprecate the app, and have a self-hosted browser interface with storage on the server, synced to a git repository for backup.
No, because it fails to support the feature of running virtually anywhere.
For many people this is the #1 feature. Everything else is just icing on the cake.
Who cares about an app that is 2x faster but doesn't run?
