There have been several examples recently, a couple from today:
i am a uk citizen and have a 2 year holiday visa for canada. can i visit my family in England
was edited to:
i am a uk citizen and have a 2 year work permit (IEC) for canada. can i visit my family in England
with the rationale edit question to match info in OP's comment (I see no such Comment).
The time to come from terminal A to terminal C on airport Pistarino, Buenos Aires
was edited to:
The time to come from terminal A to terminal C on airport Pistarino, Buenos Aires (EZE)
and the tagging changed from rome to airports argentina buenos-aires eze
(Separately, note the advice here).
Neither of those who posted the above Qs has yet reverted [†] and both are only "Member since today".
If they never return then radically changing a question to make more sense (and in particular to better fit the As that each Q now has) is to salvage something constructive out of a bit of a mess.
However, without feedback from OP no one can be sure that radical changes truly reflect the OP's intent. If the changes do not do so it seems new users in particular may decide that what they really did want to know is never going to be answered on TSE, so manage without or look elsewhere.
(Separately, if whatever is asked and however badly is edited "into shape" by other users this hardly motivates users to bother to take care with their post.)
[†] I have just seen one of the users did revert, though with a Comment that does not clarify much: the visa is a working holiday visa (but more like "holiday visa" before the change to "work permit (IEC)").
