I studied and used English as my 2nd language since I was born compared to Japanese as a major at university so I'm more comfortable reading and writing in English.
And I started reading scanlations since around middle school it's mostly out of habit too. Now that I'm working I can attempt to purchase series I find myself enjoying.
Paying per chapter in official manga websites is less of a hassle than buying Japanese volumes as of now though. (I don't know anything about kindle and stuff, also sometimes (in amazon for example) purchase is just plain unavailable for many regions).
Attempted to buy physical volumes through amazon once only for those not being able to get through customs, leading to a refund.
