Ownership of private stock corporations is centralized no matter who the majority stockholder(s) is. What those companies do is increase decentralization. Opera provides a builtin VPN, which makes it's users far less able to be tracked, banned, or otherwise impeded in their communications online. Poloniex is a gateway to fiat for cryptos, clearly advancing decentralization financially. BitTorrent is a mechanism to crowdsource data downloads, one of the most powerful decentralization mechanisms online. Steemit I assume you grasp how it's a decentralizing mechanism online.

Ownership of those companies was always centralized. Tron putting them all under it's umbrella reveals the company is seeking either to use those technologies and foci to advance decentralization online, or to prevent them from being useful for that purpose. I find them not doing the latter, which they could have done easily as soon as they bought them.

Tron has clearly not EEE'd any of those companies, in any way.
