The way I look at it, if I want to talk about my hand till the cows come home in hopes of convincing my opponent to do what I want them to do then that's fine.

If someone else starts talking about my hand when they aren't in the hand that's not fine

If someone else starts talking about my hand when they are in the hand and it's not HU or their turn to act then that's out of line and should be seen as a rules violation. The problem with this is that with shows like HSP and PAD now people are seeing pro's do exactly that, and while they also show those pro's getting commented at or apologizing they also show them not getting penalized in any way. This has the same impact on players entering the sport as WPT showing only all-in-fests did initially, people see this as the way to play if it's their first or only introduction to the sport and mimic that behaviour.

This is not a good thing but there is nothing that can be done to stop it until it's introduced into the rules...problem is that could cause more hassles, if I recall correctly they made a rule in one tournament (possibly WSOP) that you couldn't do anything to try to coerce your opponent to do something (ie talk about your hand, comment on their stack, etc) and a player got penalized for doing just that which takes away one of the tools in the arsenal for a lot of players.

We don't want to get bogged down in rules to the point every hand requires players to be rules lawyers but we also need to ensure that even the hint of cheating or collusion are nowhere near the game if we want to prove to the govt. that it's a fair game with all players on an equal footing and it comes down to skill not chance or cheating.
