@Konaburd a large rather unfriendly company can potentially kill the fediverse, through a strategy known as 'embrace, extend, extinguish'. imagine this (simplified) scenario:

1. A majority of the fediverse chooses to accept federation with Threads. support is good, improvements are made, and everyone is happy for now.
2. Meta adds new features to Threads that don't work with other instances
3. Users upset that these new features break on other instances, and are forced to switch to Threads as the other instances become 'obsolete'.

This happened numerous times in the software world. For a company like Meta, this is quite realistic.
