Established company with any kind of brand recognition is definitely worth it, because of the disruption that could be caused by someone getting the trademark before you (e.g. you could be sued for using their trademark, you could lose your web domain, etc).

For a non-established company, no point. I struggle to see the point for an OSS side project, too, unless there are plans to turn it into a paid product at some point in the future.

I wrote a story about how this plays out, 10 years ago, still relevant: https://startupnews.com.au/news/the-buildkite-story/
