The thing about the release of "Holiest Thing" was that at that point there were still legitimate questions as to CBS/Paramount's intent, and genuine concern that the lawsuit meant the end of fan films. Its release and the subsequent silence from TPTB was a strong sign that only Axanar was being targeted, and quietly quelled the rampant paranoia.
It's easy to forget that in the immediate aftermath of the filing there was real fear over the "end of fan films" and a lot of the fan backlash was defending Axanar not out of love for Peters or even Axanar, but out of fear that all fan-films would be shut down, and what this said about CBS and Paramount.
Thankfully a lot of that support has fallen away with the release of NV, Horizon and others in the days since, when it has become clear that the only affected series will be Axanar, and that the target on Axanar meant that there was a clear and distinct difference between it and other fan-films, at least in CBS/Paramount's eyes.
Whether you agree with their decision to file suit or not, it's pretty clear that they view Axanar as an exception to the generous (albiet unwritten) rules they've laid out for fan film makers.
