That is my point. There is nothing Blizzard can do about this addon because it isn’t using their APIs to pull or use it. There is even more precedent that addons like this are perfectly valid because their stance has always been that communities (even temporary ones like pugs) are well within their rights to be as inclusive or exclusive as they want so long as it isn’t against the otherwise defined rules in the TOS.
For example, me and my 3 guildies are well within our rights to form random groups or join LFG heroics and just kick everyone out until we get someone who we approve of using whatever criteria we make up (and are free to change or modify at will). It would certainly make us donkeyhats by any reasonable community standards, but we aren’t breaking any rules per say.
Just like it isn’t against the rules for donkeyhat tryhards (or anyone) to ruin a key and 4 other people’s time by abandoning the run before it is completed because some or all of the group ends up not meeting their self-defined metric for acceptable standard. In fact, plenty of past threads and notable posters here have very predictable stances and takes and are in full support of that behavior believing “bads don’t deserve completed runs for failing” and other such drivel.
Blizzard LETS the pug world be an unmoderated lawless mess short of people going blatantly against the hard and fast rules of the TOS and many people want SOMETHING to try and otherwise weed undesirables out.
So even though a commendation system isn’t a foolproof system or a yelp like feedback system is rife to be abused (someone showed me all the false comments I got the other day), Blizzard can’t (or rather shouldn’t) keep their head in the sand about this forever.
You can never have subjective data and turn it into objective metrics but humans can bridge that gap and at least make more educated decisions using that subjective data and applying whatever value and weight to it along with purely quantifiable objective information to ultimately help influence that decision.
I also highly doubt this addon will be the next Raider IO, Details, or DBM and I think the developer(s) should quit hiding/evading questions and criticisms and work with people to perhaps make something better (since it’ll never be perfect), but I dont fault them for at least taking their version of a stab at it since Blizzard refuses to actively help shape this community into what THEY want it to more or less be.
