Honestly even if they had coded this to anything other than MacOS I wouldn’t use it, I’m not too keen on learning a software that’s developed by a team that archived their previous project, given how popular atom was when they decided to archive it it concerns they could just do the same with this one.
On the plus side, the fact they stopped Atom development has allowed our community fork of Pulsar to flourish and it has seen loads of active development over the last year. I do find it hard to blame the original team, it was clearly a Microsoft thing to make sure they put all focus on VSCode.
