I think sky may be doping on a small scale or gaming the rules, but not any more than other teams. I agree with the post above about how much of a turn off it is to watch them dominate races the way they do. Hoovering up the best talent to use as disposable super domestiques is a luxury no other cycling team can afford. It's ruined the race for me.
But the anti-brit stuff is all a bit silly. It's clear that even with 'help', it's a stretch to take someone without any natural ability and turn them into a grand tour winner. Its also very clear that Brailsford (who I despise) is not wrong in his methodology of taking good track cyclists and getting them to physically transform into skeletal, tunnel-visioned freaks. It's also worth considering that much like the NFL, cycling as a sport is heavily reliant on physiology that can be moulded to fit the purpose, so expanding the pool of potential cyclists as happened around 2000 in Britain (there has been a big push in schools since then) was always liable to yield results.
Put it this way, I was in a minority at school in the 90s cycling. There was very little visible success to emulate and events weren't televised. Now there are cycling tv shows and coverage of track events, every grand tour etc.
I guess from outside it probably looks worse, but I strongly believe you could do the same in pretty much any reasonably developed country and over 10-20 years get a return. The tour wins are 90% down to sky working out a formula to protect their lead guys.
Anyway, as someone also mentioned, the rank hypocrisy of people talking about this from France leaves as bitter a taste in my mouth as if anything. Virenque, Cofidis and Festina (with a huge French contingent) were the people I looked up to as a naive youngster. They were some of the people who truly destroyed the sport.
On Thomas, there seems to be a bit of an attempt to ignore his past performances and the context, eg: the crashes and injuries when in good form. The guy has more pedigree than most, and this has been a weak tour. Froome is off the asthma and there is no natural big opponent now. Dumoulin maybe, but everyone else is just not good enough to beat the soul destroying sky train.
