I was never arguing that. I'm arguing that your "we don’t need magazines since it’s all part of the same universe" is complete nonsense that's not relevant to anything being stated.
Though if I'm gonna argue about your initial point, you're also wrong and foolish there, albeit it to a lesser degree. Unfortunately X, the platform formerly known as some shit, is a "Big Tech" company. In fact it's one of the biggest. Now, you may or may not be familiar with this, but the "Tech" in "big tech" is short for "technology", marking Twitter, the platform formerly known as shit, a monolith in an extremely large and broad industry.
As a result, that which is news-worthy for such a monolith is precisely what technology forums such as !technology@lemmy.world are for. It would also be relevant if Facebook lost 50% of its valuation in a day. It would also be relevant if Instagram started giving employees free heroine. It would also be relevant if Google harvested all the world's oysters in search of black pearls.
These companies are so large they they, defacto, are tech in a manner of speaking. Just because you're tired of hearing about some rich dork whose racist father hates him, the man formerly known as Eyore Must or something, doesn't mean that it's any less of a tech company, and doesn't make news about it any less "about tech" as an industry.
