These “demographics” are not being excluded, ATM they’re just being inconvenienced.

Have another look at that list. People using public libraries are not necessarily tech savvy; more likely the contrary. People whose ISP chose to implement CGNAT don’t necessarily even have any idea that they are sharing a WAN IP address. AOS ≤6 users are likely clueless; they will just blame their phone and buy another.

I’m not sure it’s fair to say all Tor users are hackers considering Tails is simply a matter of booting with a USB stick inserted. Many VPN users are avg Joes just trying to reach BBC or torrents. VPN services have had to lower the bar to be usable by low tech folks.

Not everyone is a tech wizard of the highest order, so I really can’t fault their web masters for using what’s easy and convenient.

I agree it’s much more likely a case of ignorance than malice. But nonetheless they have a professional duty to become informed about the consequences of their choices. Using CF is a proactive move¹. They are responsible for excluding people and should be held accountable until they get it right.

¹ OTOH, 4 of those parties have apparently outsourced to “Nationbuilder”, whereas Défi apparently did their own CF deployment. Whoever is behind Nationbuilder owns their incompetence. It’s reasonable to expect an outsourced contractor to know what they’re doing. The political parties should choose a different contractor who can do the job without excluding people.

Digital exclusion is a big problem in Belgium. Current politicians are dismantling analog infra and forcing people online for government transactions. And those gov resources are often broken and/or exclusive. People are often forced to disclose more info than necessary (in violation of the GDPR minimisation principle). So it is actually becoming quite important to elect people who oppose digital exclusion.
