I think it happens in just about every realm when you get close to the innovative edge, especially in tech: you can be really excited about some aspects of $SHINY_NEW_THING while recognizing that it has serious drawbacks in other realms--possibly realms that people expect $SHINY_NEW_THING to excel at as a contender in the space.

Personally I love Tesla-the-company and my Tesla vehicle because of the innovation it's driving in the space--and I'm willing to tolerate the ways it falls short due to how incredible it is in other ways.... but I do try to be up front about those shortcomings when I discuss it, at the risk of being one of those "I love my Tesla, but..." people.
