Re: Low margin?
When this last came up, I went looking at accounts - I've kept the results I found, but not the raw data.
The worst performing telecom I could find had an ARPU of around €280 per year - so the "average" user paid them a bit over €23/month.Their profits were around €25 per user per year - not huge, but not awful - somewhere around the 8% you found for Deutsche Telecom. When I looked over a 5 year basis, their annual profits per user varied between €23 and €27. So fairly consistent over time.
The best performing big tech I could find had a profit of €10 per user per year, on ARPU of €15 per year. By the percentage margin, this is incredible compared to the worst performing telecom - over 60%. When I did the 5 year check, though, their ARPU varied from €6 to €21 per year, while €5 per user cost of doing business was the lowest they'd managed, so profits swung from 10% margin (€6 ARPU, about €0.40 in profit) to 70% margin (€21 ARPU, about €14 of profit)
You'll also note that, in addition to the bigger variation in margin over time, the big tech company consistently had an ARPU lower than the telecom's per-user profit. On a pan-European basis, the big tech company made more than the telecom, due to being present in all EU member states, not just a subset, but the telecom made more money per user than the big tech firm. It's just that the big tech firm was able to book much more of a smaller pie as profit, because its expenses were much lower.
This all leads me to the belief that the telecoms are merely annoyed that they can't claim more of the total revenue, because no-one's willing to pay them more for the service they provide, and that they're whaling on "big tech" because people see that big tech makes large global profits, and don't look deeper than that.
