I'd hesitate to make this generalization. I need to use slack on a macbook for work and it crashes regularly. I tried out VS code and it also would crash on occasion. Worse than that, coworkers of mine have rolled bug-ridden electron apps that we're required to use. There are plenty of non-electron apps that are stable.

This is quickly becoming one of those things I can't stand, especially when there are open source/free options out there. No, I don't want to use your homegrown application unless there really isn't a good option out there. And if that's the case, make it a good tool and release it OSS and try to get some traction behind it.
Most 'home grown' corporate apps I've used are dependent on internal resources, processes and requirements. They'd be useless to anybody else, there are no alternatives anywhere at any money and in many cases you can't do big chunks of your job without them.
I don't like that slack consumes some many resources. I love vscode so I don't care.
