AFAIK ayahuasca is legal in the US for religious purposes, isn't it? Similarly in Utah Mescaline is legal for consumption with "sincere religious intent".
German prosecutors are not independent but have to follow the authority of the ministry of justice. So in principle, politicians can stop the prosecutors. They would rarely do so as that would be the bigger scandal in the end.
I payed 140 Rupees per month for 10GB per day in January (Vodafone). Special deal on the poush mela. We tried, yes it is throttled after 10GB to a slower speed but continues to work. Who needs 10GB per Day anyways? I had to read and re-read the contract, i was first assuming it's per month but no, daily reset. And it works in all indian states. Tell me where on this planet there is cheaper data?
At volume (e.g. an order of 1000 exactly same robots) you can get a 2m industrial arm with 200kg of payload, 2m/s speed and 2m/s2 accel for around 10k€. It's close to the material cost, that's why robotics companies venture off into new field such as collaborative robots, medical robots etc. where margins are still higher.
Robots are a component of an automation solution. Most solutions will be heavily customized in ways that are specific to the individual customer - who would usually interact with an integrator and not a robot supplier. The integrators, usually small companies with less than 10 employees buy most of the robots on the market. So as a robotics company you have to primarily focus on the integrators and offer a no-bullshit component to them. Extra fluff like the camera and touchscreen will be useless in 95% of cases. Why would i want to pay for that as an integrator?
Additionally, rumor has it the production was too expensive. Maybe due to the fluff. When you're pushing robots on the market below your own cost while the competitor beats you price wise while making a profit - you're going to have a bad time.
The initial aim to provide a robot with nylon bearings and series-elastic actuators wasn't a success, the pivot to the standard industry approach of harmonic drive didn't save them as there was no price/performance advantage over the competition.
I believe quite a few people in the industry saw the Rethink robot like toys that weren't meant serious. I don't know about the actual performance, but the image was there. As an industrial customer you want bulletproof and dirt cheap and not fun to play with.
