Its a fair point about the need to invest in additional software to just be on level with other players. There are however fairly cheap HUDs available or even free trial versions, so I think, its a little bit of an overblown concern.
The far larger issue in my opinion is all the ofter software, which exist, not to mention paid training sites like Upswing Poker to mention just one. I am currently struggling a bit to beat the games, I play, so I can move up further. Something like 10-20NL cash games and 3-5$ tournaments.
And I am currently debating, if I should dig out the cash to purchase a subscription for ICMizer and the Upswing Lab. This however is 150$ per year each, so its on a completely different level than the 100$ once and for all, you need to pay for PT4. But I am sure many of my opponents have paid for these subscriptions, so I am at a systematic disadvantage to them, if I dont do the same. This is not something,
poker sites can stop, so in that sense I do feel, that all this focus on HUDs is a bit out of proportion and like fighting the last war.
That being said I think, its perfectly fine, that HUD free sites or games exist. In that way people have a choise, and how can anyone possibly be against a choise. Its not like, its a human right for me to play at exactly
partypoker with a HUD, just like its not a human right for someone else to play on HUD free tables on
pokerstars. Sites can set their TOS, as they want, and as players we then wote with our feet and our rake money.
My issue with PartyPoker is the lack of hand histories, which I have written about many times before, so no need to repeat it again.
