"It's opensource, so people would likely have caught this issue." Lol, practically every CVE is on code you can read.

"It's opensource, so it is going to be a better engine in the long run." Citation needed.

This is probably true due to a sort of survivorship bias. code you can read is much easier to analyze and test and report. Closed source internal code has a lot of security by obscurity built into it. Not to dismiss security by obscurity, I am sure it keeps an absolute frightening amount of code safe.
