Try Masterbatedone if you don't like Twitter - Elon Musk
Mastodon is not a particularly new platform, but in 2019 it saw significant growth in India. After twitter suspended senior supreme court attorney Sanjay Hegde's account at the time, a large number of people migrated to Mastadon.
Twitter appears to be performing pretty well despite these campaigns. An internal memo that The Verge was able to access claims that during Musk's first week as owner, Twitter's daily user growth reached "all-time highs." According to the report, Twitter's "monetisable daily user (mDAU) growth has increased to more than 20%, while Twitter's largest market, the US, is rising even faster." For perspective, twitter reported in its second quarter report that it had 237.8 million monthly active users.
