It is true; I know someone it happened to recently. I also know someone who was studying to join the Catholic Church; but because they did not attend regularly to the Mass, they were told not to bother. They were thoroughly lectured on what a “grave sin” it was. if that’s not control; I don’t know what is.
I guess you don’t know what is?

You cited an example of somebody studying to join the Catholic Church, so he’s not a full member to begin with. (Error number 1, since you can’t disfellow someone who isn’t a member of an organization in the first place.) Second, the reason the Catholic Church has a year-long process for admittance is to make sure people understand all that will be expected of them. As you said, the person got a thorough lecture on the definition of grave sin. If they weren’t willing to accept that definition, then they don’t fully believe what the Catholic Church believes and shouldn’t join at this point. (Error number 2, the expectation wasn’t forced upon them, but explained at length. The person was given a choice.)
Third, is that the Catholic Church doesn’t even have a process of disfellowship! We do have excommunication, but that is incredibly rare and only used in cases where the actions of the individual are so contrary to church teachings as to actually threaten the integrity of the church and the soul of the believer. A person would never be expelled from the Catholic Church for not going to Mass, but they
would voluntarily place themselves in mortal sin. They would, of course, still be Catholic, and be able to participate in the sacrament of reconciliation (confession) so as to remove the stain of sin. (So, error number 3, there is no disfellowship in the Catholic Church.) Error number 4 is simply faulty logic. Let me explain.
I want to take piano lessons. If I start the process, but then fail to show up to the lessons several times in a row, wasting both my money and the instructor’s time, and then proceed to get lectured for it, is that control? OR, is that simply explaining what I did wrong and questioning my commitment to the process?
And speaking of “the money” I wonder if I should tell people what this poor fellow I was talking to who pays this money says about those who can’t pay any money! Making people pay for intercessory prayer??
JWs sure are not the only ones who try to “control”
Hmmm… when I was a poor college student, my grandmother died and I literally barely had enough money to feed myself and pay my bills, and still stay in school. I asked my priest for a Mass to be said for my grandmother, and he suggested a small donation, like $5. That particular week, I had to buy airline tickets to the funeral, and literally needed that $5 for gas to get to the airport. I explained this and the Mass was said without problem or expectation of payment. I will say that I did volunteer my time, the one thing I could afford, to the Church for some time after that. I did this on my own; the priest did not ask me. Further, the donations that are asked for go to the direct maintainence of the church. None of it goes to the priest, at least in our parish.
