I think it is also worth reminding that the Free License, which is the only for which splash screen + analytics are required, is an entirely new option introduced with JUCE 5.
As such, no previous user of JUCE is retroactively forced to use it.
Instead, I think old and new developers that use JUCE should see the Free License as a new alternative that they may wish to opt-into if they like. If they don’t, then the two other routes (GPL or Paid) are still there as they were before, nothing changed for them.
(in short, I think @jules in the summary post above could have added a big fat [NEW] tag next to the “Free License” entry, to make that more prominent)
small edit: the above being said, I also agree with those who think that the presence of the analytics stuff could/should have been mentioned together with the splash-screen in the email/website communication. Doing otherwise gives the feeling that ROLI would have liked it not to be really noticed.
