I'm thinking out loud through the logical ramifications of why anyone would be upset at a proposed change to the current practice.
Because if there were a large number of people who would be willing to donate, and the only reason they're not donating is that these emails are being sent to spam at elevated rates... that would kind of justify the administration targeting Google's spam filtering practices here, on grounds that Google's practices are having a material, negative impact on the democratic political process on a partisan basis, whether intentional or not, no?
If the spam filter is applied equally, but one actor is doing a filter-triggering action more than the other actor, then no, it would not justify the complaint.
