it's still leaking information. let's say there are 5-6 companies that all work in the mystical cloud-painting sector, you lump them together and publish data about the sector. before there was nothing available now there's an average. and obviously partial information is very useful for exactly those with some other partial information. this is why OSINT is very effective. it's possible to piece together enough constraints on these datasets that in the end the likelihood of a successful deanonymization is unexpectedly high.
