I am building a web analytics platform that in theory could be a decent substitute for GA. I'd like to share some notes with you. In addition to all you have mentioned, GA has a problem now called adblockers. It's actually not a problem for them as much as it is for website owners. Depending on the country, independent agencies say adblockers are present in more than 30% of browsers. I can't imagine what kind of business intelligence tool provides that amount of error and is still considered ok.
