I've never understood why people get so hung up on the word.
Canon is exactly what it claims to be - whatever the author wants to be accepted as their body of work.
It is not some kind of law that is punishable by death. What is more important is what you enjoy - I don't think I have ever sat down to watch a movie or read a comic and thought "damn, this isn't 'canon' - I'm not allowed to enjoy it any more..."
It seems to me there was a massive period when I was growing up where anybody could pick up the SW license and print whatever the hell they wanted - from 1977 right through to well into the run of Dark Horse comics in the 90s. SW spin-offs were an absolute mess continuity-wise. Fact.
That is why there was a need for a canon (or various levels of 'canon'😉 in the first place.
Whether you approve or not, it is only relatively recently that Lucas has taken a more active role in managing the spin-off material himself and approving what should be considered canonical.
Personally, I like the original three movies first and foremost, I'm also in the minority who thought the prequels were worthwhile. However, I also love stuff that I grew up with such as the Marvel comics that barely make sense in context of the original movie, let alone in comparison to other areas of the expanded universe.
But they captured something of the tone of the SW movies, and I love them for what they are - the fact that very little of that Marvel run has anything to do with canon has nothing to do with me enjoying it.
It all depends on your point of view. It's funny everyone hates Lucas now for "messing with things" and "doing things just for the money" etc etc... the fact is, the damage to the EU was done back when Lucas was the golden chlid, when he was happy to schill out the Star Wars brand to any old story to make a few bucks, creating the mess that the was EU as we entered the new millennium.
Really, he is doing the "right thing" by finally getting involved and taking some control of the EU, but the upshot is that he is now contradicting the mess people fell in love with and attempted to make sense of in the first place.
Like I said, I think everyone is better off just watching and reading what they enjoy.
