Bear in mind that it's a Russian site and they have a huge problem with producing or buying radiation-hardened chips. So it's kinda 'sour grapes' attitude.
Also, this site was chosen for publishing because it was easy and because they actually give you some audience. Getting the same attention at Medium would be much harder, and a copy of this text, which I posted at LinkedIn, got something like 60 views. LinkedIn has a great publication editor, by the way. If you have an advice on some better place where I could publish scipop texts about microchips, that would be really appreciated.
The problems with satellites are mostly due to competely different factors, not the state of radhard IC design. For example, transition from imported to domestic EEE components is painful, as the demand is much higher than industry's capacity.
