HOA to enforce mandatory fees to subsidize for-profit business

Our HOA, which is currently ran by new developers of the neighborhood, are in the process of changing the covenants to require new home buyers to pay mandatory fees for access to a pool facility owned by a separate for-profit business. Those of us who already own homes in the community will be given the option to opt into the agreement, but like the new home buyers we will have no ownership or say in the for-profit business and will be required to pay this fee indefinitely. Is this legal? The pool facility does allow members who live outside of our community to join, but these people will not be bound by the neigborhood HOA rules. A few of us in the community are tring to figure out what recourse, if any, we can take should this covenant be made. Can anyone provide any information?
