The problem with Ubuntu is that trust in a package manager is a basic criteria when evaluating a distribution. Once Canonical had violated that trust and shown its attitude with privacy violations, data collection, and default opt-in, you should stay away from anything that comes from Canonical. They didn't get away with what they did, but the mindset behind their actions is part of how that company is run and what they might do in the future without letting you know. They were trying to establish an income channel by knowingly sacrificing the user's privacy and security. That's a no-go in my opinion.
