I used to, but not so much these days. I'm not really interested in commercialising my photography (it's a LOT of work and its hard to make a decent living from) and I generally don't mind people sharing them non-commercially. Commercial use is a different matter and I do keep a bit of an eye on it (https://pixsy.com/ https://pixsy.com/ is great for this), but in my experience it is rare for them to get used inappropriately without being asked permission first. I also don't put them online at high enough a resolution to be useful for printing which cuts down any offline abuse. The story you linked is an interesting one, especially given how heavy handed Getty are when it comes to misuse of any of their images in the reverse situation. Personally I think what Getty have done here is completely unethical but given the public domain nature of the images in question they might be in the clear here.
