I can see the reasoning, but i think making the ban more surgical in nature would be a better approach, ie lifting the ban for specific things such as research and outreach. I think lifting the ban outright sends the message that if enough places discriminate then its ok. Atkins mentioned making personal connections, and i do think thats important, but im not sure that lifting the ban completely is the best way to go about forging personal connections. That being said, im not sure what would be the best way, and a mediocre idea is better than no idea.
Id like to see a migration fund and social net fund for people fleeing discriminatory legislation, but that is a whole lot more work to implement than bans like this one.
Cryptpad.fr offers spreadsheets and up to 1gb free storage, and if i recall right theyre using foss. Im unsure about the dashboard youve mentioned, but id hazard a guess that you can perform automatic calculations based upon cells in the spreadsheet, to for example sum all expenses.
