I'm pretty peeved with the pdf-only-can't-borrow-can't-resell model at present, thanks to RM Express Additions. The problem's not soluble without lots of DRM, though, so I guess we're stuck with this.
I am not an expert on the legal situation, but as I understand it, it varies from country to country in any case. But the point of the address message is really "we need you to buy stuff, please don't steal it" rather than a legal discussion that would in any case probably not be true across all markets, particularly on cases like printing multiple copies from a single pdf, and sharing those about (something that has long been done, back to the photocopy days, for spell lists and attack and critical tables).
ICE don't really have the luxury of the cheaper or free pdf models pursued by other companies; Paizo, for example, sell all their fancy RPG pdfs for $10 and still seem to sell a lot of hard copy (and the rules themselves are all OGL), but as ICE can't produce print runs their pricing differentials are effectively going to be constrained by the grim realities of PoD. Eclipse Phase is actually free on pdf, I think, but that'd mean people would just print their own and have it bound at Kinkos and no PoD monies for ICE.
I'm reassured that RM will be set free if it can't make any money, not because I want AA not to make any money but because I would hate for RM to disappear completely (something I believe Mr Seal has never wished to contemplate either). That's a really cool commitment.
I would note that, as a RMC fan, maybe I am more likely to get "static" in any case*. I'm happy to pay, of course -- I can afford it and I think that RMC/RMX is great -- but really I'd like to be able to buy all of it. However, as the bizarro WotC decision to pull all .pdfs showed, they have much less longevity for legal purchase then hard copy, which I can at least normally buy even if I pay more than cover price, when production and official sale ceases.
If stuff appears which I like, I'll happily pay for it. I do feel somewhat worried that the stuff -- that interests me, I mean -- might not appear, but I'm just an individual with my own preferences which certainly may not reflect the market. There's a trickier situation with stuff I like, written already, which won't appear, though, but it's hardly the first game in which that has happened (for pdfs, at least, all TSR/WotC stuff ever is in that boat).
*Although I'm not claiming this with certainty, or anything like that; if someone pitches an RMC idea which looks like it'll do OK, I'm sure it'll get full consideration. I've never, however, detected much enthusiasm for RMC/2 from some of the higher-ups, either the game or the tactic of reformatting RM2 into a new saleable form (pretty sure there was a GC editorial in which the wisdom of putting effort into that was questioned), so if efforts are focussed onto games in which I don't have much interest -- RMSS/FRP or HARP -- then I'm not going to be complaining that it was unexpected (any more than RMSS/FRP fans felt about the static nature of the book output for those games).
