Being a business owner I know what the social media landscape is like. Small businesses can't limit their advertising potential by sacking off these terrible platforms. Reading our website stats its very clear that lots have stopped posting on social media but people are still looking at it and that still helps drive sales.
So however nice and politically correct it would be to ditch all the horror socials, for a business its not really an option just yet.
If everyone moves to Bluesky it helps and there is more engegement on there than Twitter now.
Everything my business does is to spread across all platforms then we let natural selection take effect, Threads is dead, activity on Twitter(Bot central) is pathetic along with Instagram. Facebook is still engegement to direct customers.
My ethics say close all the accounts, its just not an option in this modern world, I expect lots of small businesses to feel the same.
Enjoy your spare HP, don't rush to fill every last space, this is not like filling sticker books. Resist the urge to 'complete' your rack, its never complete so just relax.
