This is a fair summary of what's happened, but the idea that UEFA did this on purpose is more debatable. A lot of what created this situation wasn't the work of UEFA, but the work of circumstance: e.g. the growth of international TV markets, which are starting to dwarf the resources available from any other stream. A lot of it was negligence for failing to see that this is where the game was going and by the time they realised it was a problem (and the threat of clubs breaking away is now entirely real and completely against UEFA's interests) things had progressed too far for them to do anything about it.
They knew it was a problem ten years ago when Platini took over. He attempted to try and open up the Champions League with various proposals (even minimal ones like giving Champions League spots to cup winners) but the clubs wouldn't buy it. A European Superleague could be an improvement if it were an open system that had some means of promotion/relegation from domestic leagues, but what we'd actually get would be even worse. At least some people in UEFA are attempting to make things more equitable, the European Superleague wouldn't even have that. It would be like the NFL - a completely closed shop run by a small number of clubs that have all the resources, all the best players, and no interest in letting anyone else join unless they'd benefit financially from it.
