According to JJ Redick most players do want to finish the season out in whatever way possible, so I'm not sure the league changing to a more negative outlook on completing the season is player driven.
I'm also not buying the optics of finishing the season being an issue. Most people I've talked with would be happy to see the season resume in some fashion. I think it's really only a vocal minority pushing back against the idea of resuming play.
My guess is this is a logistical issue more than anything. Hopefully, they figure it out. I would definitely welcome a completion to the season if they can pull it off.
I think you have it mixed up. It's a vocal MAJORITY that don't want to see the league continue. I have friends in the sports industry and they tell me athletes, for the most part, don't want to continue until they are 100% sure it's safe.
JJRedick can say the majority of players want to resume but if that is true, and I'm not 100% certain it is, but a majority could be 60%. If 40% of players don't want to do it, the NBA shouldn't force them to.
If you try force that group to play, there could be major unrest within teams as some players might blame their teammates for putting themselves and possibly their family at risk.
Everyone, league front office, owners, players, television personnel, radio personnel, arena personnel, support personnel all have to be 100% behind this or else, don't do it.
