Looks like if these ETFs get in a legal fight with the government for any reason, the legal fees are coming out of the trust balance. Even if they waive their regular fee for a while, you can still be hit with charges for "extraordinary" things.
Seriously? That's your response? legal fees in the event of a government legal fight....
10's of millions of $ of legal costs for setup of the ETF's, plus all the employee training, research and other human resources, plus who knows about infrastructure, logistics, office setups, travel, meetings, but that's all OK because the ETF issuer can still charge for costs of legal fight with government if it happens
You put all that effort to find this tiny little thing, you should instead put the effort to understand why the ETF issuers are waiving fees for at least 6 months as well as lowering the fees from the get go to basement level. Come on, man, do better, for yourself...
