Then I must've missed the whole customization thing in ME1 because there was none, except the relatively MARGINAL upgrades you could apply to weapons/armors AND most of which you would basically sell for money considering you got about a million of them during the game, mostly useless and meant to be sold (and this is coming from someone who regularly equipped ALL of his characters, not just the active trio).
You see, I have nothing against complexity and customization (hell, I LIKE them, not to mention they're usually integral to every half-decent RPG), but from what I've read the ME2 cuts out the annoying parts of ME1; sub-par customization, loot and all that is great, but the end result is fundamentally the same - get the best possible stuff. Now, if ME1 encouraged and rewarded gear experimentation for some added bonuses (which it doesn't) then I would grieve for it's absence, but given that ME2 removes the annoyance of basically changing EVERY member's gear after you get better version of it, nothing's been cut... nothing useful and interesting at least. I don't need customizability and complexity for their own sake if they don't contribute to anything.
Like I said, haven't played it yet so I don't know the details (nor these things you mention as annoying and which are, to be honest, mostly your subjective opinions), but I'm glad that each character now has a recognizable getup and look. It sure beats seeing my awesome Garrus, or any other character, in a neon-yellow armor because it has good stats.
And considering that ME1 was never a full-fledged RPG but a TPS with some RPG elements I don't see this as some kind of "betrayal" by BioWare. Just because it's made by BioWare, it doesn't mean it has to yet another hardcore RPG, something that ME1 wasn't in the 1st place, anyway.
