Does Hatzalah charge for their services?
You the one of the few examples of mosdos that are able to survive on only donations. Most don’t.
Shuls charge membership, yeshivos and Bais Yaakov charge tuition, mikvaos have fees, and in a similar vein, kosher food costs more, tzitzis, tefillin, shaitels and other items required for frum life are also not free.
We want people to go to shul, get a Torah education, do mitzvos and keep the Torah. Yet these things are all not free (some are subsidized and there are tzedakah funds to help, but they’re not free).
I think your complaint against TAG is very unfair.
