Ah there was a time when Prime Day was kind of fun, a Christmas in July kind of feeling. But now Amazon is just so loaded with knock off junk that doesn't work, spam postings, review manipulation, etc I absolutely dread shopping on Amazon for anything other than something I need right away, can't get in a local store, and don't care if it breaks in 2 months. I've never given less of a shit about Prime Day than I do today, and that's even without factoring in the price manipulation noted by OP.
There's a reason behind the weird brand names. The seller has to have a trademark on their brand name in order to participate in several Amazon programs, such as their predictive analytics. The easiest way to guarantee your trademark application succeeds is by ensuring it can't possibly conflict with any existing trademark, and the easiest way of doing that is by generating a random string that's (somewhat) pronounceable.
Lmao I told my wife recently the company names that dominate search results look like somebody just wiped their hands across a keyboard and said yep that's the name alright.
Service/platform enshitification is extremely frustrating. Incidentally, it seems to have a very direct correlation with the greed and sociopathy of the CEO/owner.
