It's our responsibility to know
There's been a bit of a thread on the Blackburn Cycling Club facebook page about UCI rules, some of which is ranting, some is not very constructive, some is tilting at windmills and some is complaining about the UCI or CA not doing enough to tell us what the rule changes are. Some is fair comment and it's all well intentioned (or at least, mostly ...). In my role as a moderator on the BBN FB page I've had no need to delete anything, so it's well behaved.
With regards to the dissemination of the rules, in some other equipment-specific sports, for example motorsport (CAMS) it is a requirement that each year competitors purchase a rulebook and adhere to the rules. We don't have to buy a rulebook, we can just download it for free (cheaper!). It is still "our" obligation to read and understand the rules and if in doubt, to discuss the rules with a commissaire to seek clarification. I have had reason to do this recently with the 5cm/aerobar rule change. So whether or not the rules agree with your philosophy, it is OUR (everyone who races under the umbrella of the UCI) obligation to know the rules and keep track of them. In particular, coaches need to be up to date. Yes, this is a little bit of work to do each year when rule changes get published and YES it can be inconsistently applied at races by well intentioned but not necessarily up to date or well informed commissaires, but it is still our obligation to know the rules of our sport. It's a lot easier these days to do so with the advent of social media, websites and so on. The following website may be of use :
