Apple One Inconsistent taxation for services

[Jashue]

Reviewing my the services I get through the App Store I see some strange inconsistencies.
Year to date, I've been charged $15.49/month for Netflix. No Tax.
HBO was $14.99 until April when it became $15.99. No Tax— Until June— when it WAS taxed my local 8% rate, totaling $17.27. Why the change?
Up to May, I was charged $6.99/month for Apple TV Plus. No Tax.
I switched from ATV Plus to Apple One in June. The $16.95 turned into $17.23 because of tax of 1.65%. Why wasn't ATV Plus taxed?
I subscribe to Apple News for $9.99. No tax.

I'm not sweating the money. It's not a lot of dough. But I like knowing exactly what I'm charged. I don't understand the inconsistency.

No idea what jurisdiction you are in, but in some places not everything is subject to sales tax. In some places, newspapers don't have sales tax, so its possible that there are jurisdictions that have exempted services like Apple News as well.
