If I say, "X is too much hassle" and someone replies with "Good news, I put a bunch of PHP up on Github", I'm not seeing less hassle. I'm seeing more hassle. Now I don't have to just worry about a half-dozen vendors, their possibly-janky products, and their willingness to spend 30 years supporting something that fell out of fashion. Now I can also worry about trying to glue all that together with somebody's hobby code that, if the average open source project is any guide, will be swiftly abandoned.
