Sadly, people will find anything complain about.
I'm never sure what someone means when they say that.
- There is a person who will find something to complain about in every situation.
- Given a sufficiently large group of people and a particular situation, you can always find a person who will find something to complain about.
I think some people feel anger towards an imagined person satisfying the first condition. But, in reality, the thing triggering the anger is most often the second. And usually, for any situation, there is some person negatively impacted by it. It's OK that they speak up and present their issue.
Certainly, the Electron aspect is a non-issue for me. I run a number of highly regarded Electron apps. But, I do understand that the memory load is reputed to be high for Electron apps. I suppose having a number of them running on an 8 GB computer could be a disadvantage. But, knowing there's a problem is not as simple as looking at usually misunderstood numbers in Activity Monitor.
Some have complained about security vulnerabilities that have been reported in Electron. However, a lot of people insist that open source is safer because it can be reviewed. Electron is one of the big open source projects that is definitely heavily reviewed. Known security vulnerabilities get patched with plenty of visibility. A closed source, native app might be better or worse with respect to security; it really depends on the sophistication of the developers.
I find 1Password's Electron app to be particularly well done and have no complaints about their choice. And remember, it's only the user interface that uses Electron. The core guts of their app that is responsible for safeguarding the data does not use Electron.
