A friend of mine is involved and I had some talks with him about this story:

In a timely manner 1) Neato does good development 2) Neato cuts corners, does outsourcing, good developers leave, only shitty internal developers stay there 3) Vorwerk just want to buy a product from them and stamp their name on it 4) Vorwerk sees that the code quality is shit and Neato blocks the changes 5) Vorwerk buys Neato and fires all Neato staff, out of good reason 6) No one want to fix their shitload security bugs of the old robots, so the servers are closed to not create additional fallout
