Kind of comparing apples with oranges.
Arca never had a website, is still as far as everybody knows a running business. Nothing has changed for them sofar, no customer has any reason to suspect there will be a significant change in the (near) future.
Things are slightly different for Leaf. An announcement from Kodak that is wants to get rid of stuff which might or might not include Leaf, the deafening silence where as normally at least one Leaf employee would have reacted almost instantly. The 'news' that Leaf might or might not survive. The 'news' of the take-over but without a lot information around it. The Afi which has been proudly introduced only about a year ago that might or might not be taken out of the product line. The failure of F&H that is building those machines, etc..
You don't really want to compare this with Arca don't you?
All of this just might go over but I can certainly understand many clients being careful and potential clients holding off or choosing other options. Sometimes open and direct communication is the only route. Personally I would not want to lose control by expecting reasonable people will call me when my company is in muddy waters. I would take control and call these reasonable people myself and probably I would also include the not so reasonable to see if I can reason with them

Sure you can expect a lot from customers (potential or not) but wouldn't you want to keep things in your own hand? All IMO naturally.
Anyway, I keep my fingers crossed for Leaf and certainly hope they get their vehicle safely on the road again.
