In the sixities the government was paying but nowadays in the Netherlands much is project based so one can only be sure about funds for a few years.
Serveral sites, also scandanavin ones if i remember well, have disappeard are changed funding. I know a huge biodiversity site which is chaning from one governmental, provincial, NoN Profit NGO to another but probably goes well funded if everything goes public after their commercial abonnement system failed. There is enough public need but not enough public money. As tax rates go down for companies companies are getting more environmental and society aware (I hope, poldermodel).
I thought CalCal (California Science??) lost a lot of its budget last years.
May be off topic, but sending emails and updates is expensive ?
And following people to ? I am thinking of unsubscribing taxons and places.
