No this is fine. I think they used to have a one-price rule (or best-price rule) but I don't think that's been the case for quite a while.
If Elon M is true to form the $11 or $7 will generate a return to individual talents, perhaps, citizen journos available on demand outside the Wolf Street fool's bauble.
If it's $7 on the site why $11 in the app and not $10? Taking the 30% cut from $11 means Musk/Twitter get $7.70
$11 a month for some extra Twitter features and a badge of honor? Pass.
No, $7 a month for that. The other $4 is if you want to make Tim Cook richer.
