. Just a little humor. However, my point is that perhaps Marriott or timesharing in general was not a good fit for you. All of those concerns you raised happen in all timeshare instances. Commissions being raised happens in businesses in general. In fact, Marriott does not even have to offer that service. Many timeshares don’t. Points devaluation happen with all systems. However, we must remember that some timeshares don’t even have a rewards system to offer. That is just an additional perk we happen to have because Marriott is a hotel system. I get nothing like that with my Diamond Resorts system. Managing the resale market is a joke because it is almost impossible. The only one that has some success is Disney and I am not sure if they control it. They are different because of the Disney parks that are attached to them. Any real estate is based upon what buyers will pay. Buyers are willing to pay for Disney due their parks. Encouraging weeks owners to switch to points is not a bad thing. There are many owners who prefer points. I at one time wished that Marriott did have a points system. Since my Diamond Resorts has always been points based, I like the flexibility if being to stay two or three days instead of a week. I particularly like being able to fly out on cheaper flights leaving on a Tuesday or Wednesday. 
I don’t feel a week owner is shafted. As a week owner I feel I am protected the most. I have the guarantee to use my week.
But those issues are shafting weeks owners. Timeshares, as the contract you agreed to on purchasing says (POS is a contract), should be bought to use and one should not expect returns on rental or sale. I don't see one issue you're raised that is negative to usage of the weeks system. No one could populate some potential issues related to availability due to the DC system, that would be a legitimate discussion although at this point it's only conjecture and in reality the DC system has likely been neutral or even helped weeks availability.
Were any of those included in the contractual obligation? The answer is no and specifically there is wording that non contractual services are not guaranteed. Timeshares change, that is the one constant. If the system no longer worked for you and you voted with your feet, that's appropriate. But don't confuse non guaranteed services or your personal situation with breach on the system side.
I agree but I am still looking for examples of where weeks owners have been harmed by changes.
So sorry.

My first question is still valid for those companies that are not using ROFR, which I recalled from reading, again not paying attention to the boards.
I will try to do better.
What systems don't have ROFR? Besides the discussions here so does Bluegreen, DVC and Wyndham. If the question is how do they decide to be active ROFR and at what level, I don't think any of us know directly. In general they use ROFR to prevent firesafes and push new buyers to retail rather than resale. But they also might take the chance to make a few $ they might not make otherwise. Given the high profit and marketing costs on the new properties, they have to get the properties at around 50% of retail just to break even compared to a new property and that means they're competing with their retail business in addition. They also have to move properties they get from foreclosure due to maintenance fees or mortgage defaults. They also have to have the liquidity and decide that's a good use of those dollars.So sorry.

That's not accurate I don't believe. Marriott put in ROFR with Grande Ocean I believe as the first circa 1991-92. DVC had it from the go 1991. Pretty sure Bluegreen had it from the start of their points system if not before with only fixed weeks. I can't speak for anything else.
