Probably not for every agency. More importantly, what would the point be? There is no decision you can make in the course of your workflow that would influence an agency’s internal storage systems. When submitting documents, your choices are email via MS Outlook, paper letter, or sometimes fax (which likely traverses MS e-mail servers). That’s it. Given those choices, it helps to know which the couriers are involved and what they see. It does not help to know about processes and tech you have no control over.
Exceptionally, you might also have the choice to not interact at all, in which case you can avoid their internal storage. But that is a rare option with public services as gov interactions are typically essential. Would you move to Germany over it? Probably not. So if you choose to live in Belgium and the gov chooses MS for their data storage, you are trapped. But at least you still have your choice of couriers.
This is never going to change anything as the vast majority of citizens are going to use email if they can. If you really want to make a change, support parties who fight for that, like PTB in the link above.
I do cast my insignificant blunt drop in the ocean electoral vote once every 4 or so years, which is not mutually exclusive with taking other actions. But a single ballot has very little influence. I also vote every single day with my wallet and my data. That’s far more important and carries more influence. You can’t make significant change with your ballot alone.
W.r.t the election, I scrambled last minute to learn about voting options. I ended up voting for Ecolo, which had some pro-FOSS positioning (public money → public code IIRC). Glad you point out PTB, which superficially seems equally reasonable on digital rights.
Also, with bpost reducing its collection to 2 times per week, good luck.
Thanks for the link. That certainly reinforces the importance of using postal mail which is apparently under threat to shrink and further reduce service quality. I hand deliver a lot of my mail which does not directly help bPost, but then the recipient always responds via bPost because I withhold my email address from recipients whose address is MS hosted. So I am helping bPost indirectly this way. bPost’s continued existence is important for maintaining people’s ability to be offline at a time when the gov wants to force digital transformation down everyone’s throat.
Indeed I know it’s rare to overcome the tyranny of convenience in this way because I even had to clear a spider web to open a mail slot for one recepient. I have also encountered mail slots that are taped shut.
I would love it if 1000 more people would do the same. Or even better, 10,000. The vote would count then.
