Excellent point. I had forgotten about this. I work for a non profit so I’m ok, but yes you should absolutely check the terms of the license before using. On the upside, almost everything is markdown files in regular folders, so you can fall back to vim anytime.
Everywhere I’ve worked it didn’t matter if I used my equipment or theirs. All IP I created while employed there was the property of my employer. If you’re in the USA, check your contracts.
