Go may be more polarizing than a lot of languages. It makes tradeoffs that aren't as exciting, which turns people against it, I think.
There are plenty of legitimate reasons to choose a different language, so it makes sense to figure out what's important for oneself and go from there. The only problem is that it's hard to know all of the aspects that may be important without trying a tool out... so we do, quite reasonably, turn to blog posts with other people's opinions.
I do think it's good to differentiate the opinions of people who have really worked with the tool vs. those who are just e.g. complaining about Go's error handling because they're used to exceptions but they haven't done any significant work with Go.
For deciding on whether or not to learn a language: I'd say it depends on _why_ you want to learn a language. If it's for getting a different job, then look at the kinds of jobs you want and learn the languages/skills to do that. If it's for pure knowledge, then learning languages that teach you something new are useful. Go's concurrency might be interesting in that regard. Rust's borrow checker is certainly interesting.
