You're not wrong, they're just faking excuses they can still continue developing their project while social distancing they can still use those apps to communicate and discuss about their project.
Some of it are true and mostly are doing it just to hide the fact that their project is complete failure. I joined this campaign xcard and now they are even gone and no udpate at all. They keep saying before that they will be listed on top exchange but ever since they keep on reasoning that due to covid but even before it happened their project does not have any progress at all. Im not expecting a good outcome anymore from them and decided to forget my promotions for few weeks.
If a project is bound to fail even from the start because of its poor team development then we should not expect anything from it anymore even if they are making another excuses. Covid 19 pandemic has made a lot of troubles but when it comes to online discussions for the project development, it won't be affected anymore by this pandemic. Maybe the project has really no enough funds to sustain for the success of the project so it will surely end up as a failure.
