cURL: https://curl.haxx.se/legal/thename.html, so it seems he has not obtained a trademark on this in the US and lives in Sweden, where trademarks aren't a legal thing.
wget is a GNU project (now at least, originally?). They seem to (makes sense) have a thing against acknowledging trademarks period. So I'm not sure it'd make sense for them to even try to enforce a trademark should someone make a product named (or alias their product to the name) wget.
Trademarks aren't a universal thing, not every country or culture will have an equivalent concept, legal or otherwise. And if products aren't trademarked then claiming trademark abuse is inaccurate.
