> To support ongoing innovation in the High Altitude Platform Station (HAPS) communications industry, Loon transferred a number of stratospheric ballooning and networking patents to partners working in similar fields.
Hard to say for certain of course without any public records with regards to an IP transaction or patent/FCC filings showing the transfer of patent assignees. Google and Fidelity invested $1B in SpaceX previously (2015), which leads us to the thesis that Loon died because of Starlink.
