Not a chance in Satan's realm would I let a TSO open my sealed meds let alone
stick something in it that could contaminate it. I would be screaming for a supervisor.

For the record, it was a 32 oz. Nalgene. Very nice bottle. Makes you wonder if the TSO was going hiking that weekend.
I would have demaned a three striper before letting them take it. I always take one of my Camelbak bottles and have never had an issue. On my last flight the TSA was playing the gate check game (before boarding I only saw them pull aside a big chested blonde and a black Muslim guy. Imaging that

) and walked by three of them carrying my full bottle in plain sight without them even blinking. On another trip I asked one of them that was standing around (again imagine that) if there was a nearby fountain so I didn't have to walk all the back down by the restrooms to fill it. To my surprised he pointed one out that was semi-hidden that I had walked by and missed. Maybe I've just been lucky.
