With you in general, but in this specific case, the whole thing seems healthy:
- Many companies (including competitors) are sponsoring LE, so the funding should be quite robust
- These companies are probably winning from the web being more secure, so the incentives are aligned with you (contrary to say, a company that offers something free but want to sink you under ads)
- the vendor lock-in is very weak. The day LE goes awry, you can move to another CA pretty painlessly
There are CAs supporting ACME that provide paid services as well.
