A lot of us use software for free, but as we all know everything comes at a cost.
In the case of free software, a substantial part of this cost is often absorbed by the people that develop it, because it's where their heart is.
Ikey Doherty is going to develop Solus full time. Leaving your dayjob brings uncertainty, risk, and in his case, financial impact. Solus has seen a lot of momentum lately, which means the community of users has the opportunity to turn that uncertainty into appreciation and reward.
If you use Solus perhaps now is the time to consider becoming a Patreon for a few dollars per month. Doing your bit becomes huge if enough people do the same.
I don't know Ikey, I don't tend to agree with him all the time, and I don't use Solus. If you think this post is rubbish by all means feel free to move along. If not: visit https://www.patreon.com/solus and do your part.
