Thing is, XI is likely still pulling in solid money. Supposedly they have what,
350k or so subs? At $13 a month, that's around $4.5M. According to
their financials, the Digital Entertainment division had an operating income of 7,781 million yen, or a little under $99 million, for a six-month period.
If they averaged around $16.5M/mo from games, and XI is probably consistently netting them $3-4M in profit every month, then it's a significant source of income that they'd not likely just want to let slide.
