When a store/business is bought out, the new owners usually(always?) make changes. Sometimes good changes and sometimes poorly thought out ones.

Look at Lands End, and WM.... to name only a couple.
As for blaming "Covid", like any other external threat it gets used to scapegoat any change that was already being contemplated.
(Like a worldwide deadly pandemic cares about our convenience or our politics....)
We have seen a number of smaller companies around here that were on the edge of extinction for a long while finally fold in the last couple years. Sad to see, but they were suffering from an unsustainable business model for quite a while before the final stress.
We still have one independent chandlery and one independent marine electronics store in our fair city, but the future is always ... uncertain.
