Is there really anything to worry about?
Seems like #Theads and #Mastodon are two entirely different things. No chronological timeline, no hashtags, tons of ads, no lists, no ability to see posts from those you follow, everything fed by their algorithm. So little control of your experience. Whereas we are free to explore. Mastodon is like a hiking trip. This seems more like a trip to the amusement park. Some people love amusement parks, others prefer to wander more freely.
