A "guided tour" isn't a democracy... and any group larger then 3 bikes is "transport"... especially in alpine terrain...
While it's true that most guided tours are not democracies, I think the tour operator can certainly make it more flexible. I engage my tour members every day (and during the day) offering a couple of routing options and letting them pick if they want a route with narrow roads, high open passes, perhaps a cable car stop, etc. I poll them every day as to whether they want an early lunch or want to keep riding, do they want to cut the day short due to intermittent rain or keep riding, etc. My groups are small enough that we are very flexible.
"larger than 3 bikes is transport" may be true if you live and ride there as you do - we have Euro riders go by us frequently, but if you're from North America you appreciate the opportunity to ride some of the best riding in the world, be it 3 bikes or 8 bikes. I've seen outfits like Edelweiss ride with everyone essentially in a line with a leader and a sweep. On my tours the faster riders are in front, the more relaxed riders in the rear, everyone goes at their own pace. We tend to stay within sight of each other in the valleys transiting from one pass to another and then get strung out a bit enjoying the riding up and down the passes based on each rider's skill and pace, but if everyone is experienced it only takes 1 - 3 minutes to regroup, not a big deal at all.
