@Cockycent:
You can continue to play mental gymnastics. They're both stealing from mangaka and I will continue to laugh at anyone who argues that 1 is better than the other
You are speaking as if Oda is conjuring chapters every week all by himself.
The One Piece chapters we are enjoying every week is not the work of Oda alone, but also his assistants, the editorial staff, the graphic designers, the marketing team, the printing company, the distributors etc etc. All of whom also needs to be paid.
Are all those people part of the "greedy company" and therefore, by your logic, do not deserve your support?
I mean, at least "I read scans because it comes out early" or "I read scans because I don't want to pay" are reasons I can comprehend. You don't have to agree with them but you can see why they are valid reasons for some people.
Your "I read scans because I hate greedy companies stealing from mangaka, so I'm supporting another group of greedy people who are also stealing from mangaka" is just an attempt to justify something you know isn't right, but you just want to feel right when doing it.
