This is completely misleading - the logo for Helium Blockchain Alliance is not associated with Robert Longden's presentation (starting at 8:33) but rather the previous presenter's discussion (name unidentified).  Longden's presentation is clearly about the Hyperledger Fabric and the importance of that to the construction industry.

The Helium Alliance logo appears to be just a paid sponsor logo for the event which is an extremely common and acceptable business practice (along side of the Hyperledger logo).

I sincerely appreciate RzeroD taking the time to document that the Helium Alliance in fact presented nothing to the industry at this event other than a sponsor logo and actually promoted the importance of Hyperledger to the construction industry.
