If you care about things beyond the operations, the Proton boss came out in support of 47's adminstration with regards to regulating big tech IIRC. I'm not aware the Mullvad chief did something similar.
Proton works well. But it's designed to be the basket for all your eggs (VPN, office suite, email, etc.). They want you to use all their services and push for upgrades to the highest tier. I found their customer support you be ... very ... slow.
If you need port forwarding, AirVPN is another option. I think they're cheaper than Mullvad but it's held together by dedication and duct tape. It works okay but read their website first to see if you're okay with how it's set up.
There is a process called reconciliation that gets triggered in the senate in a budget impasse situation. I would say it typically involves a whole lot of horse trading but at the end is a bill that can pass with a simple majority. So I don't think either party will be able to drag this out indefinitely or just to the midterms.
Dragging this out generally is a bad idea for Democrats. The cult following of stable genius is going to accept the negative consequences longer as long as they get fed a narrative along the lines of "we prevent immigrants from getting health care and drain the swamp of lizard people." Or whatever. The Democrats will feel their feeble support dwindle when unpaid government workers are done with their savings, which will happen before the cult runs out of patience. The whole battle is mainly fought on the backs of people whose only fault was choosing a career in government. The Democrats will take pity on them and eventually agree to the least dehumanizing compromise you can negotiate at the "12th" hour.
