The purchase cost of the WLIP was as set by Davis and there was no set expiry time and the device was locked by Davis to their own servers. Davis can not turn around now and say this is a subscription device or it's no longer supported because it's too hard to fix, don't work with this, don't work with that, Davis created this, users purchased this as per the Davis terms & conditions at the time and Davis will dam well support it and some users won't be letting Davis forget this.
As for current status, intermittent downloads on some at times but long time between downloads and way not up to date, still totally dead on others so very inconsistent.
