From that post:
> I may build an Electron app that patches the Electron app… so far, that’s what makes the most sense to me. But we’ll see.
Even if this was against the ToS, could it be stopped? I didn't know one Electron app could target the other.
An Electron app consists of two parts: HTML5 (which can run Javascript, but within a browser-like sandbox), and native Javascript code, running under Node.js with no sandbox whatsoever. The native half of an Electron app can do anything to your filesystem (including the parts that contain other applications) that any other native app can do.
A year ago or so, I was able to start desktop Slack with a param to open the dev tools port open and use something like puppeteer to control it (at the least, I opened dev tools inside of Slack's Electron app). Not sure if that is still the case.
