Your government has asked everyone to stop going to work. Not to stop going to work once they've gone through bureaucratic steps to get permission to not go to work.
You should stop going into work immediately. Any harm this causes is due completely to the company deliberately sabotaging themselves. This amounts to blackmail: "I'm going shoot myself in the foot to force you to stick around to stop the bleeding".
The information you have is information that everyone in the office has right to know immediately, not as the company deigns to give it to them.
Any downvoters should explain why they disagree with the above, or why the following is not a reasonable email in light of the above:

I have recently learned that [IT guy] has disabled VPN access on our laptops, and then told the CEO that there is no VPN, to try to get us to continue coming into the office. As there is in fact VPN capability, and any lack of its functionality is due to deliberate acts by agent(s) of this company, I will no longer be coming into the office. I will be making use of whatever remote work capability is available to me. It is up to this company as to what that will be. I recommend that others follow suit.
This will get the issue resolved much faster than "raising a ticket". It is a basic principle of economic efficiency that losses should be sustained by those most capable of preventing them. As long as you're the one bearing the burden for their fuck-up (and yes, even if it was a unilateral decision on the part of IT guy, the company is still responsible), they don't have much motivation to hurry.
