Do some reading on "clinical equipoise" and you'll start to get it.
The control group in a drug study would not place someone currently on strong medication onto no medication. That would violate the ethical principle of equipoise. The subjects in the control group wouldn't be given a placebo; that would be horrendously unethical. They would be given either the current gold standard of care or the new drug/procedure being tested. The researchers and subjects would both be blinded to which they were receiving. For instance, an RCT comparing hydrocodone to a new med would have both arms take a new pill, but both pills look identical. One would contain the medication they've been taking and the other would contain the new drug. That's not what the OP is talking about though.
I'm not super experienced in clincal trials, but the study the OP was a part of doesn't sound like a double-blinded RCT; it sounds more like a limited-rollout experimental kind of clinical trial, where certain people are allowed to elect to try out the drug. This is not really a scientific experiment that would have a control group, but a limited opt-in rollout of the drug.
I don't think there area any areas where both TW and Comcast operate. So it won't change the number of choices for anyone.
Its not their mess, its tanks owned by third parties:
Often built for gas stations during the 1950s and '60s highway construction boom, the tanks corroded over time, spilling gas and diesel with potentially cancer-causing chemicals under properties and into aquifers.
The oil companies are paid to clean up the pollution caused by these tanks constructed for, operated and owned by third parties. The oil companies are chosen because they already have extensive inhouse expertise on the subject, so they are ideal for doing it wholesale.
Chances are, most of these tanks have been abandoned and their original owners do not exist, which is why local government step in.
Nonsense! They each outright own a large portion of such stations, either directly, or through secondary companies they set up. Not all of them are franchises.
The beta is bad. It's so bad. The comments are reduced in screen width about 50%. Subject lines are deemphasized, scores are minimized, etc.
The discussions are the reason to come to Slashdot, and the beta trivializes them entirely. It looks like the comment section on a generic news site.
The comments now look like an afterthought, whereas they used to be the primary focus of the site.
