“Oh you built this house with one of our hammers, so it’s ours actually.”
The problem with companies like for example Adobe over let's say DeWalt is that they actually have a pretty strong grip on it's target market.
If there was only one company that made tools to build houses i'm sure eventually they'd try to pull the same crap if they could get away with it.
You can totally see the same kind of walled garden thinking in things like battery platforms for powertools. Most people buy into a brand and never go elsewhere but there's litterally zero technical purpose behind this other then toolmakers going through lengths making their batteries only fit their tools.
The best option here is to just tank Chrome's market share instead of making something that's obviously not ideal, work.
