I think it's a good idea. Cert prices vary, and there are reasons for it, and companies would rather pay for stability than save money.
By that logic, the tax accountant could argue that they should arrange a company's finances so they pay more tax, in order to pay for more "stability" by funding the government.
In this case, I think it's safe to assume that a $200 contribution to OpenSSL won't repay the contributing company $200 of improvements.
