The impact of Covid-19 on many businesses around the world is very sad.

That said, it's less clear to me that the medium-term impact will be pro-incumbent or pro-large company. Big incumbents tend to be less adaptable and to benefit from large fixed cost barriers to entry (e.g. real estate). We're seeing a lot of nimble small businesses migrate to online business models far faster than the behemoths they used to struggle to compete against.
