You can’t claim shit about equality for all and access without materials, when discussing byod. Make up your mind.
There is PC access, and then there is byod access. It’s a false dichotomy to demand choosing one or the other particularly when only one of the two is available to everyone, and harmful to people’s rights if you simultaneously design a system of workflow on the assumption that one replaces the other interchangeably.
They are different services for different purposes. Don’t let the fact that some tasks can be achieved with both services cloud the fact that some use-cases cannot.
Everyone has access
Everyone has access to a PC running Firefox. Not everyone has BYoD WAN service access.
byod is covered for 99% as extra convenience.
Firefox is not the internet.
It’s not just convenience. It’s the capability and empowerment of controlling your own applications. If the public PC doesn’t have a screen reader and you are blind, the public PC is no good to you and you are better served with BYoD service. If you need to reach someone on Briar, a Windows PC with only Firefox will not work.
You aren’t being treated poorly, instead, you have unreasonable expectations.
This remains to be supported. I do not believe it’s reasonable to only serve people with mobile phones. Thus I consider it a reasonable expectation that people without a subscribed mobile phone still get BYoD WAN service.
Data persists both in the cloud, or on a memory stick. Free options exist.
None of the PCs in any library I have used will execute apps that you bring on a USB stick (but even if they did, the app you need to run may not be compatible with Windows). Also some library branches disallow USB sticks entirely. So a restricted Windows PC cannot replace controlling your own platform, regardless of the convenience factor.
(edit)
But strictly about convenience, I also would not say it’s fair for a public service to offer extra convenience exclusively to people who have a subscribed mobile phone and not to those without one. That would still be unequal access even if you disregard the factors not related to convenience. It’s still discriminating against a protected class of people.
