If the 2 items on the frontpage are irrelevant for the subreddit that would make it impossible to post threads which are actually relevant.

Relevance of the posts on frontpage is also affected by problems I described above, meaning the thread that shouldn't be posted in /r/technology has (almost) equal chance of being on frontpage as the one that's relevant.

I have no idea how to solve the issue, maybe a modqueue like page where moderators can isolate specific threads until they're approved?

But just removing all threads if 2 (similar) already exist has too many issues.

It has less issues than removing all threads period imo.
