The legislation is aimed at opening up the APIs of all messaging apps/companies which meet their criteria for being a "gatekeeper". Apple simply happens to meet those criteria.

Your article called their data an estimate without giving any insight into how the data was estimated, other than the caveat that it may include users who only used imessage for sms.
You mean anecdata without hard facts are meaningless??? You don’t say.
Not to mention, where was the anecdote in your article? There's no anecdote there in a 1.3B estimate, for all I know it's just some random reporter's guess (backed up by who knows what), whereas an anecdote is at least a hard fact, just one with small sample size. If I don't know how the estimate is made then I probably actually prefer the anecdote.

Could it be that maybe your anecdote is meaningless outside of your bubble?
