> It seems that anyone can file a bogus copyright claim to get an article they don't like removed from Google's search index
This has been known for years. Copyright has been abused for many many years in this sense.
And Google is very well known for their completely absent human-in-the-loop support, so that doesn’t help either.
While that is true, and Google deserves are shaming they get for their terrible handling of DMCA, lets try to be real. Autoaccepting all DMCA takedown requests with zero verification is simplest and cheapest approach to be complaint. Failing to delete a file is tho only way to be on hook for any repercussions.
