Off-topic comment but it seems like some kind of trend to intentionally use double negatives in comments. I understand that sometimes using the double negative could be an important distinction, e.g. "not uncommon" does not necessarily mean common, but in this case I think one has to go out of the way to say "not infrequently." Maybe it's just me but I had to re-read that sentence to be sure I understood what was said.
Could just be regional idioms; I think I picked that phrase up from some British folks who made a habit of understatement. It isn't especially friendly to the reader, I'll admit (there, I did it again!).
The phrase ``not uncommon'' is not uncommon in the UK.
I mentally cross out the "not" and the "un" or "in"; then it reads correctly.
e.g.:
"not uncommon" becomes
" common"
I don't think this is regulatory capture at all. Regulatory capture is when those charged with making rules meant to limit the powers of a group are in bed with that same group.
