It seems the actual number is 43% of those surveyed use an ad blocking tool at least once a month, so a lot of those may only have their ad blocker installed on their PC, plus the bias that comes from only having the answers of those who responded to the survey
Still that’s a fairly overwhelming number of people who feel strongly enough about the topic to install a plug-in. I’m sure there’s a portion of ‘no’ responses that are not aware of what adblockers are or do
Even to install on Android Firefox it took more effort than I expected.
