It is stupid to buy something just to avoid taxes. If it helps you grow a business - sure. But not to avoid paying taxes. As I said it depends on your goal. If you want your business to grow, have the best seed round or in general company valuation - yeah, reinvest. But if it is business that you do to make a living, it is stupid to spend everything just to not pay taxes
You can downgrade version on fdroid, thats what I did
