Exactly my thought. It is not based on 'ability to hide money from taxation' or anything like that. Just in lower corporate tax rate (even then, it's lower still in Bulgaria and Hungary and yet those countries don't have much to show for that). Also we have tax exemption on dividend income for individuals, but again, plenty of countries have that, it's more of a norm than an exception (no country could hope to attract any high middle class or rich immigrants unless it provides that, it's a baseline expectation).

And selling golden passports to Russian oligarchs until 2020.
