limited by intelligence agencies, corporations like John Deere, Apple, and the entire entertainment industry
What do you think of commercial platforms like CrowdSupply with e.g. https://www.crowdsupply.com/search?q=tpm where OSHW solutions can be sold to individual and companies?





A good rule of thumb is : does any of the participant maintain the backend?
If not then you are dependent on at least a 3rd party. If that 3rd party is not entirely open, meaning at least
then basically you should consider that this 3rd party owns your group, there is no expectation of privacy in it, it can be closed in an instant, messages can be modified without you knowing it, etc.
TL;DR: bad.
