You can ask him if you want (iaace on discord/pateron) but my guess is people were misusing it or riot asked him to stop? Riot definitely didn't take away the ability to see past names, because the API for getting info about a match (https://developer.riotgames.com/apis#match-v5/GET_getMatch) includes the names people in the match had at the time the match was played. Iirc rewind.lol gets your match history across multiple seasons, so it'd naturally have name changes from your old matches.

This site shows old names in parentheses (eg LookMyBigBrain), but it's limited to season 13 NA matches.

You could also write your own simple script to do it, which would be slower than rewind.lol was because rewind.lol stores a lot of old matches, but would still work. This also may only go back a limited number of matches though...maybe riot changed the matchlist by puuid API to only go back like a year and not all the way to season 5 or whatever idk.

I'll post the script in its own comment, to run it you need to go to https://developer.riotgames.com/ and generate a riot API key then copy it into the top of the script, and have python and requests/sys/time installed, then you run it like "python3 rewind.py joblinbarrel"

Also to speed it up instead of checking name in each game, this script checks the last 1 out of each 100 games
