You don’t need a coding bootcamp

Also, absolutely no-one coming out of a bootcamp would say they're ready for a senior or even mid-level developer job. Categorically no-one. I have no idea where the author got that sentiment.
They are recruitment 2.0, in which they are trying to farm developers. A lot of the bootcamps in the UK have deals with big firms to allocate X developers per cohort to them.
Its a great business model, people pay them to essentially be motivated to learn publically accessible data, then they get some "help" finding a dev job. Then the hiring company pays the bootcamp a fee as well.
Not great for existing developers who then spend time babysitting the bootcampers, who I would say require more effort and time than graduates or juniors.
