Yes-like Meta, or Threads, or Apple, Glean, Element, X, Zoom, etc.

If you choose a generic word for your brand name, don't be surprised when a bigger company chooses the same generic word and ruins your SEO. This has happened before. Maybe it's not fair, but it's extremely foreseeable. It seems much easier to me to choose a creative name in the first place than to risk a legal battle wherein you have to prove that really you should be able to use that dictionary word because you thought of it first. As other commenters have pointed out, since Threads (Meta) and Threads (software) operate in different spaces, Threads's (software) claim for exclusivity is tenuous anyway.

Precisely. If you chose your product/company name to be a common word in the english language you should expect it to be more difficult to exclude others from using it too. I don't think there's anything wrong with this, it's just the consequence of a non-distinctive trademark.

This should apply for both threads software and meta.

I'm a bit surprised how many people here have sympathy for companies trying to enforce exclusivity over common names. Let anybody use "threads" if they want.
