Renault may have stated publicly at the end of May that they remain committed to F1, the indications are that the French government (the majority shareholder in Renault) is under very considerable pressure from unions and public opinion alike, to find economies within their peripheral operations rather than continue to close or amalgamate car manufacturing operations.
The Renault/Nissan conglomerate has already been badly damaged by the scandal surrounding Carlos Ghosn, and there isn't much public sympathy in mainland Europe for the closure of car production plants. The fallout from Coronavirus means that Governments must revive their core economic drivers, and manufacturing industry, together with the associated supply chains, has to be helped back into production. If you are a French politician, you're going to gain more support (and votes) by prioritising jobs over what could be seen as supporting a rich man's sport.
Renault are no longer supplying power units to customer teams - their engine department shed around 50% of posts during the 2011-2013 period when their engines were winning everything, because they were installed in the Red Bull. Senior Renault management saw an opportunity to downsize the facility, which led to a talent deficit to develop the turbo-hybrid units, which Renault were so keen to see used in Formula 1. The result was a lack of outright performance from the Renault unit, which managed the occasional result, but only when Mercedes and Ferrari failed in the same race. Development was hampered, and the team appeared to limp from one disappointment to another. Customer teams, Red Bull in particular, made no secret of their disappointment, and their decision to dispense with Renault and put their faith in the hitherto dismal, unreliable Honda spoke volumes, despite the luxury of having Toro Rosso to try the Honda units for a year first.
The major strategical decisions at Renault are made by civil servants and politicians in Paris, not the FIA or FOM. This article appeared on Pitpass a few days before the Renault statement of renewed commitment to the sport:

I think that Daniel Ricciardo made a smart move. The FIA and Liberty have a mounting problem in that they have two, possibly three teams whho may very well disappear within the next three years, unless funding can be found from outside of their current backers. Formula 1 without Renault, Williams and (possibly) McLaren will be hard to sell to fans and broadcasters.
