I think it’s pretty safe to say that the majority of us are here to avoid another corporate takeover of our preferred platforms. It would seem to me to be a tad irresponsible to allow Facebook into our space with open arms, allowing them to hoover up our data. I would love to keep using Lemmy.world, but will happily change instances if need be, and I feel many share that sentiment.
You still can. Just block threads.net instance in things like Mastodon and Lemmy.
Your data is public in fediverse. They can scrape even right as we speak.
I would need someone to confirm this, but I have heard that if you block, then it prevents their instance from scraping your data because they shouldn’t receive your content if they are blocked, but it doesn’t change the public data being available by other means anyways.
Follow hashtags and communities that are your interest. Block users and/or instances you would rather not see or be part of. Also, you can find an instance that fits your values that is already blocking instances you disagree with.
I am mostly indifferent of Threads joining at this time, but those that are not in favor, there are options.
