actually just reading the tor guides use and warnings i think its enough to make u quite using tor. but i think this is non-sense thinking in that way, because:-
1- is there any alternatives better than tor ? if there is , then i dont think patrick will deny adding this service to whonix.
but since there isnt atm , then keep using tor is the best what advised here
2- not every attack work here then it must necessarily work there, security varies r always there.
3- tor is an old tool and till now is getting updates and their community is not piece of cake, they have intelligent team from all around the world which may give u some confidentiality about security rigidness atm or in progress.
4- reading programs vulnerabilities in general among the time , if u dont take these vulnerabilities reports as a way of “how to fix or avoid them”. then stopping the internet is the best advise here , because vulnerabilities wont stop.
