But you hit the nail on the head with such eloquence (and thanks to your post I felt compelled to launch into a bit of a rant myself, so it would seem)...
I purchased Mass Effect back in '08 off Ebay for something like $25. Loved it so much I paid $80 for ME2 Collector's Ed. in '10 and another $30 on DLC for that game as they came out. Two years later I bought ME3 CE for $85...and after enduring the travesty of 'that ending' I promptly gave all three games away (and my original Origin account) in abject disgust.
Suffice to say, my experience after ME3 made me much more wary as to how I spent my money with regards to games. Before ME3, and especially with regards to Bioware in general, all it took was an announcement of some new game/product and I'd be all "shut up and take my money!!" about it. Now, not so much...
To add insult to injury, that same friend I foisted those games on gifted me Mass Effect and ME2 on Steam during the 2012 Holiday sale (to this day I'm not sure if he did it as some kind of sick joke). Being the completest I am, I felt compelled to purchase ME3...again...this time, through Origin (after creating a new account, of course).
Lo and behold, I see the Digital Deluxe edition of ME3 for $20, and with a not insignificant amount of hesitation, purchased it. With time, I actually played through the trilogy once more (sans most DLC for ME2, including LoTSB and Arrival, as flawed as that was) and enjoyed it again (aside from ME3's ending, which the Director's Cut made merely marginally deficient instead of an outright farce).
I'm pretty sure that was the last product I've purchased off of Origin. The only other products I've purchased off Origin was Dragon Age: Origins Ultimate Edition for my original Origin account for some absurdly low (even at the time) price of around $5-6, which was actually cheaper than Steam at the time and genuinely surprised the hell out of me, and the execrable Pinnacle Station DLC for ME1 (which is the ONLY DLC for ANY Mass Effect game I've seen on sale for the PC, EVER.).
Of course, when I relinquished my initial Origin account, I had to kiss all that (and my ME2 DLC which I couldn't get on Steam and I'll be damned if I pay full price for DLC with Bioware's idiotic points for what will soon be a FIVE year old game) goodbye and start anew. Luckily, that same friend gifted me DA:O Ultimate Edition...through Steam.
So, I think I've spent roughly $30 through Origin since its inception. By comparison, Steam has successfully relieved me of around $375 per year since 2011 during their Summer/Holiday sales (not quite how to feel about that). EA/Bioware make up a rather small percentage of my Steam purchases, roughly $30-40 total, which, unless my math is off, is around 2%.
Last EA product I purchased was Bulletstorm for $4 during the current holiday sale...off Steam.
There's still a place in my heart for Mass Effect (and Dragon Age), but I'm not going to give away my hard-earned cash, digital or otherwise paying full release price for DLC, of which the newest one for ME3 will be two years old this coming March, especially when I can go buy complete A-list titles from developers that seem to give more of a damn about their fans/customers than EA/Bioware on Steam that are newer for the same price or less, and out of general principle I sure as hell won't be buying Mass Effect 4/Next/whatever or DA:I (especially with regards to how PC gamers are being screwed yet again via sloppy porting) or anything else coming out of Bioware until this particular issue has been addressed and rectified to my satisfaction and others who share my viewpoint.
Given EA/Bioware's track record, I'm not holding out much hope...
