Please as you read my answer keep in mind that the ITTF rules are for the international level, then it is up to each national association to decide if they will adopt them or not.

- I believe that the 25mN applies to all rubbers
- ITTF does not "control" any personal equipment such as rubbers and blades, instead we authorize those manufacturers that wish to use the ITTF logo on their rubbers only if the rubber meets the ITTF rules and requirements. We do not authorize blades. We "approve" only the common equipment such as tables, balls and nets. In this case we also must ensure quality.
- why not 5mN? same as why not 5mm thickness of 3 mm thickness or why 11 points and not 7 points or 15 points. Any decision is based on a proposal made and backed by many experiments and explanations before a vote is taken. 25mN was felt to be by the experts as a good level of minimum friction, based on several tests made.
- the after treatment is what lead to the rule. Not the other way around. Once the rule was made, then if you wish to play in ITTF events you must follow ITTF rules. If you wish to use ITTF klogo on your rubber for sales, then you must produce a rubber that meets ITTF rules and requirements.

Your points:
- you are for stopping to make rules on things that did not need have rules.
I fully agree

- for allowing boosters and so as long as they are not harmful (Cigarettes are!)
All Boosters we tested were found to have harmful components. But the biosters are illegal for another reason, because they alter the rubber after it has been approved (rule 2.4.7)

- for putting the sport in the first place, not the rules.
You are right, the sport always comes first

- for supporting minorities, not try to rule them away (Players with frictionless long pimples)
They are all welcome to form their own association, or to find a new way to stay in this association. No one is chasing anyone away.
