You have COMPLETELY misread my comments and missed the point.
My point was that there are plenty of other better devices suited to these tasks than a little obscure laptop with a crappy keyboard, such as an iPad or Android tablet or eink tablet, or even a phone. My argument wasn’t “hurr durr doing nothing would be better”.
My opinion is “valid in this context” because I’ve spent countless hours RDPd in to various machines and servers in trains, buses , passenger seats of cars, on the side of the road,etc fixing issues and making changes that saved literal millions of dollars at a time, and the last thing I’ve wanted in those situations was a worse device to do it on simply because it’s “different”.
Being “locked down” is irrelevant for a device used to read and write on. All those devices are also significantly more powerful than this thing.
They all also have keyboard attachments readily available across all sizes and prices.
Linux isn’t at all necessary for the use cases the author talks about. Windows would be massively overkill.
