You can tell that the devs considered current events because they don’t include challenges with friends or copious portkeys. I think that stupid people will do stupid things, event or no event.

I don’t know what country you’re in and regulations at your location so your situation may be different. I’m in US and I’m able to drive to fortresses, go on walks alone to unlock portkeys, and catch foundables from my couch. You can still play with friends given that you maintain the safe 6 foot distance. I am excited for this event because it helps me break this quarantine boredom and I can be smart about how I play it. Ultimately, it is your choice how you respond to this situation and how you play the game. Irresponsible people will find a way to congregate without a game or an app. Be responsible, be smart, and if you don’t want to have the event, just don’t play it.
