Focusing on the largely theoretical concepts of tax and law is an extremely inefficient way to try to understand Moldova, as well as a number of other countries.
Here's the full story:
I've seen publications in local[2] "press" about the case although it focuses only on corruption and there is no mention of internal company's politics there.
[1] at time I worked there it was the only source of revenue, not sure if any other product take off since
[2] yep, I'm in Moldova
In this case, it appears to be the result of a dispute between a former owner and current one. In that case, this appeal is only one side of the story, and the judge may well be proceeding based on evidence provided to back up any allegations.
I'm writing this because as much as I've witnessed corruption, I've also witnessed shady characters blaming everyone else for their misdeeds, especially the country, judiciary etc. "It's the oppressive regime that caused me to do something wrong, now they're repressing me" etc.
While I'm not suggesting the company is at fault, it is also not clear that there is no cause for what is happening. Calling for foreigners to apply diplomatic pressure to the Moldovan state without having the facts of the case is also a form of extra-judiciary pressure, much like the alleged conspiracy against the company.
Crowdfunding international pressure instead is a waste of time and their supporters' very scarce attention and interest.

"В 2013 году фирма удостоилась звания «Сознательный налогоплательщик»[4], учрежденного Главной Государственной Налоговой Инспекцией Республики Молдова."
translation:
"In 2013 the company was awarded the title "Conscious Taxpayer" by the Moldova State Tax Agency (ie. like IRS) "
and according to this http://logos.press.md/node/38228 the company was also given "Certificate of Trust" along with the title which meant official guarantee of absence of tax audits for the 2 years following that.
Edit: After spending some time Google-ing it seems just a simple case of extortion by the team consisting of a local police inspector, prosecutor and a judge, i.e. it looks like RitLabs, despite their good taxpayer status, has still missed (and seems to be stubbornly refusing) to pay some local "tax" :)
