Fist, it’s not censorship. Second it’s being done with enormous success over the years between 2009-2023. 99.9% of the data containing txs are within the filter parameters. In 2023 a filter got exploited thanks to the taproot upgrade (unintentional consequence) and that resulted in the huge abuse of arbitrary data (spam) that we’ve seen over the past 2.5 years. If this filter was fixed back then in Core 26 or 27, like it was fixed in Knots, we wouldn’t have been having this conversation.
