Who knows. Without COVID-19 they might have made a good job of exploiting what was to be the 2021 regulations. Despite the similarly bare coffers they did with the 2014 ones - helped by the power plant of course, but they were challenging Mercedes on certain tracks too. A resurgence was unlikely, but not impossible.
It's a shame when a historic team is in its dying days. It happened with Lotus (36 years), Brabham (29 years), Tyrrell (28 years), Ligier/Prost (25 years) and even Arrows (24 years), despite Walkinshaw's dodgy dealings. All bar Arrows won races or championships.
There's no immunity from hardship in racing, but it's these independent teams which have shaped F1 over the years more than most manufacturers, who, Ferrari aside, come and go as it suits them.
As a side note, I was genuinely impressed that Sauber have the 5th highest number of race starts. They're the only team of the dozens of minnows from the late 80s/early 90s which survives in a similar guise (Racing Point bare little comparison to their ancestors). Granted Sauber are branded as Alfa-Romeo at the moment, and was taken over by BMW for a few years, but it's been Sauber. Obviously there are many more races each season now than when the likes of Ferrari, McLaren and those above started, but even by season (BMW) Sauber aren't that far behind those listed above at 27 years old. Not bad for a tiny team based in a country which until recently had a long-term ban on all forms of circuit motorsport.
