One interesting consequence of Mastodon's AGPL licensing is that Gab, the right-wing twitter clone that runs a Mastodon fork, also has to disclose its source. That was how people found a vulnerability in Gab that allowed the recent "hack".
So for one example, the recent (bait and) switch of Elasticsearch to SSPL effectively means that for many actual real-world users of Elasticsearch, the benefits of staying on the official Elastic branch has ceased to be worth the costs of the license when your alternative is running FOSS Elasticsearch/Opensearch.
So to answer your actual question - presumably as an operator you want to use the AGPL-licensed code more than you want to avoid those same negatives of AGPL.
