Is it, really? Meta completely botched this window. I believe it is a company that is fated to wane, similarly to Yahoo!. It may not fully die off, but the truth is that the younger generations shun Facebook, they have this perception that it's a website where their parents and grandparents go to bicker, not where you'll find the coolest, trendiest things like you do on Twitter and TikTok. The truth is, Meta's zenith is long since past, and the simple fact that this company is now called Meta was in direct acknowledgment that the Facebook brand had begun to weaken.
I reckon that by now, Mark Zuckerberg realizes that acquiring Instagram may have very well been his best investment, it will keep Meta afloat as the "metaverse" he drummed up has ultimately failed to spring, WhatsApp, despite its strong user-base is ultimately not even close to a profitable venture and their main product, Facebook, has a negative perception amongst newer generations and has been abandoned by a large amount of people who don't agree with the overbearing "community standards" - something that Musk's Twitter has absolutely aced so far.
These platforms hold immense power, think about it - not even with YouTube's popularity and the integration of the Shorts feature has stopped TikTok's exponential growth. Something similar happened with pre-Musk Twitter, the former board of directors made of the platform hostile to a certain segment of individuals, putting intense pressure on them with a series of high-profile expulsions intended to clearly state that they were not welcome to stay and eventually went on to create Twitter clones of their own, none of which had the slightest impact in the active user base.
It's a numbers' game, Musk is anything but a fool, he is acutely aware that people kvetching about Twitter no longer being an eco chamber and how evil he may be is not going to have anyone leave the platform, especially not those who would raise their hand against it - he realizes that to drum up anti-Musk, anti-Twitter sentiment, these influencers require the one thing that they are actively campaigning against - their reach, which is comprised of active Twitter account holders. This means that the numbers game was won before it even started, the more page views and interactions, the more likely an user is to stick by, regardless of their current bias.
This is the same treatment that Reddit gave to those who disagreed with their policy changes regarding APIs, they simply didn't budge and told them to deal with it, as they know that there is no replacement for Reddit and their user base was going to be using Mastodon and the fediverse for exactly one week before they all came back grumbling at their feet again, seeking their fix.
X merely stamps it - the old Twitter is dead, all hail the new Twitter.
