There are plenty of online resources about the cult aspects of TM if you actually look.
Cults are distinct from normal religious organizations. What makes the TM-as-promoted-by-David-Lynch a cult?
The link talks about a religious organization that asked for money on a regular basis from followers. Who is being harmed there, and how? People willingly donating their money to religious organizations is not alone evidence of abuse.
"So you had to have a special kind of paste before you went to go practice your Yogic Flying, and the paste cost, like, $150, and the Yogic Flying cost thousands of dollars to learn, and then your badge to get into the dome to practice the group meditation cost $100 a month."
"It cost thousands of dollars because Maharishi said that Americans don't value things unless they pay a lot of money for them."
Also, a cool documentary, not about TM but somewhat related: https://www.youtube.com/watch?v=urMxgevzd4c
