I've heard that the Catholic Church considers baptism into the church to be for life, and can make it quite difficult for anybody to remove themselves from official registers. I don't know if there are any equivalent registers in Islam that you'd have trouble deregistering from.
Obviously, there are plenty of people around who consider themselves ex-Muslims or ex-Catholics, regardless of any such considerations. Likewise, for so-called cults, so I'm not convinced it's really a point of difference.
The difference is that Islam proscribes death for apostates very clearly in its laws, whereas catholicism does not. You're on a list, like a birth certificate. In general, you cannot force another person to erase their memory of you, but certainly not killing you would be good.
It's rare in the US, but it does happen in other parts of the world (killed for being apostates).
Not going to comment on anything else, just pointing out the obvious difference in kind here. Death is orders of magnitude worse than having your name on a list.
(This wasn't unique to Spain, but Spain was certainly an epicenter, due to a large Jewish population forcibly converted during and after the Reconquista)
I'm not going to excuse the church, but this was actually the civil punishment. The church just declared you an apostate or not, and civil authorities would punish you (BTW, most European countries still have similar laws with just lesser punishments and no church involvement... IIRC, blasphemy is still a prosecutable crime in Germany)
What about people executed for heresy in the Papal States? There are many examples, but the most famous would be Giordano Bruno, burnt at the stake for heresy in Rome in 1600.
The whole "it was the civil authorities not the Church" line doesn't really work there, since the Pope was ultimately in charge of both, even if the two were still nominally distinct.
Even in the case of the Spainish Inquisition, where the Church-va-State distinction was somewhat more real – you have to ask whether the Church encouraged or discouraged the civil authorities from imposing capital punishment on those it convicted of heresy. I think you will find that the answer was very much "encourage", not "discourage" or neutral. "We didn't execute anybody, we just encouraged the government to execute them" is a rather laughable defence.

That's literally why I started off my comment with "I'm not going to excuse the church". You're absolutely right that there ought to have been a reckoning with the consequences.
As a Catholic, I regularly attend Church and we have many people (even entire families) who either join after a long period of being away or leave the faith all together. We miss them of course but no one sends them death treats.
Additionally, many people move between denominations.
Perhaps you are confusing those with real cults such as: Christian Science, Jehovah's Witnesses, Mormonism, Seventh-day Adventism ?
I can't however speak for how they operate as I haven't studied them or been involved.
The Catholic Church in a number of European countries stopped processing requests to formally deregister people, due to mass departures after the sexual abuse revelations, which may be what they're referring to.
The tests the courts use is whether you can actually physically leave control of the organization. Having your name written down or having a spiritual belief that some ritual is permanent, etc, doesn't count as not being able to leave.
Are you asking the court to make a judgement on theological matters (i.e., the state of your soul)? Surely you can see why they don't care.
Cults are often criminal. The Catholic church doesn't harrass you for money or really reach out at all if you're on its roster. All it is is a record of your having come there, which is their record to keep. This is like saying elementary schools are cuts because they keep your transcripts on file -- a completely ridiculous assertion.
