Twitter is appointing Tesla CEO Elon Musk to its board of directors, according to a filing with the US Securities and Exchange Commission. Musk will serve as a class II director until 2024. This is a type of position that can be used as an anti-takeover measure.
This is a good observation, and I've seen similar. It's a good reminder for FOSS devs that when you copy some proprietary app you're also likely importing some capitalist dark patterns, as well. Fortunately the underlying protocol is pretty generic and not specific to the Twitter model, so it's not a complete dead end.
