I know this is a late reply, but I didn’t notice the notification. Sorry about that. What I do is, I open a free virtual card for each service. I have one for netflix, one for spotify and so on. I set the monthly spending limit just above of what they cost.
This way if I ever unsub, I can delete the card and they can’t charge me, or if they have a data leak, they only stole my deleted cards.
Aw man, every midrange phone that would be interesting comes with MediaTek SOCs. I should check if the custom rom scene is still dead for phones with MT chips… Do they still withold the sources needed for rom developement?
