Device vendors and sofware providers in an unholy mix?
According to the article there are several hardware options available to schools. Yet, these, certainly with Microsoft, are tied into a software provider. No only that, but Microsoft, it being a (the?) major supplier of proprietary software, a vendor of in-house designed equipment, and highly influential over independent hardware manufacturers' specifications (e.g. 'secure boot' and TPM), is setting the pace for ever tighter control of users' devices with, for example, TPM offering chip-level DRM. Conceivably, 'consumer' devices shipped with Windows 11+ will for all intents and purposes be locked into Windows products for all users apart from the technically savvy. Similarly, business users will notice tightening of licencing enforcement.
Not all the matters raised above need have immediate impact upon how schools use computers to support teaching. However, they exemplify a complicated commercial backdrop with priorities not necessarily consonant with those of education. For instance, Microsoft operates a mode of business akin to Tom Lehrer's "The Old Dope Peddler" viz. -
"He gives the kids free samples
because he knows full well
that today's young, innocent faces
will be tomorrow's clientele".
