Why do you assume they "feel compelled" to do this? I mean, it seems highly likely in my opinion that some percentage (possibly/probably the vast majority) are doing so as a last or near-to-last resort, but "highly likely in my opinion" doesn't strike me as sufficient grounds to write up your questions with what seems like an implicit assumption that the percentage is as close to 100 as to make no useful difference.
